WXPython: call a function with no binding or handler

I am building a small python program and I would like it to check for its ini file at startup: if the ini file it's not there then open a file dialog and write a line of it with the folder selected in the dialog.

I am using WXPython and I can't figure how to call a function while the program is running in the simplest possible way...

here's the code:

#----------------------------------------------------------------------
# A very simple wxPython example.  Just a wx.Frame, wx.Panel,
# wx.StaticText, wx.Button, and a wx.BoxSizer, but it shows the basic
# structure of any wxPython application.
#----------------------------------------------------------------------

import wx
import os


class MyFrame(wx.Frame):
    """
    This is MyFrame.  It just shows a few controls on a wxPanel,
    and has a simple menu.
    """
    def __init__(self, parent, title):
        wx.Frame.__init__(self, parent, -1, title,
                          pos=(150, 150), size=(350, 250))

        menuBar = wx.MenuBar()

        filemenu = wx.Menu()
        aboutmenu = wx.Menu()

        filemenu.Append(wx.ID_OPEN, "Ch&oisissez le dossier de travail\tCtrl-O", "Choisissez le dossier")
        filemenu.Append(wx.ID_EXIT, "&Quitter\tCtrl-Q", "Quitter")

        aboutmenu.Append(wx.ID_ABOUT, "Aide de Pic Portier\tF1", "Aide de Pic Portier")
        aboutmenu.Append(wx.ID_ABOUT, "A propos de &Pic Portier\tCtrl-P", "A propos de Pic Portier")

        self.Bind(wx.EVT_MENU, self.OnTimeToClose, id=wx.ID_EXIT)
        self.Bind(wx.EVT_MENU, self.OnFileOpenMenu, id=wx.ID_OPEN)

        menuBar.Append(filemenu, "&Fichier")
        menuBar.Append(aboutmenu, "&Aide")

        self.SetMenuBar(menuBar)

        self.CreateStatusBar()

        panel = wx.Panel(self)

        text = wx.StaticText(panel, -1, "Es tu pret?")
        text.SetFont(wx.Font(14, wx.SWISS, wx.NORMAL, wx.BOLD))
        text.SetSize(text.GetBestSize())
        funbtn = wx.Button(panel, -1, "Just for fun...")
        btn = wx.Button(panel, -1, "Quitter")

        self.Bind(wx.EVT_BUTTON, self.OnTimeToClose, btn)
        self.Bind(wx.EVT_BUTTON, self.OnFunButton, funbtn)

        # Use a sizer to layout the controls, stacked vertically and with
        # a 10 pixel border around each
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(text, 0, wx.ALL, 10)
        sizer.Add(btn, 0, wx.ALL, 10)
        sizer.Add(funbtn, 0, wx.ALL, 10)
        panel.SetSizer(sizer)
        panel.Layout()

        # And also use a sizer to manage the size of the panel such
        # that it fills the frame
        sizer = wx.BoxSizer()
        sizer.Add(panel, 1, wx.EXPAND)
        self.SetSizer(sizer)

        # Check for ini file
        self.OnFileOpenMenu(None)
        #ConfigFileCheck()


    def OnTimeToClose(self, evt):
        """Event handler for the button click."""
        print "See ya later!"
        self.Close()

    def OnFunButton(self, evt):
        """Event handler for the button click."""
        print "Having fun yet?"

    def OnFileOpenMenu(self, evt):
        # Args below are: parent, question, dialog title, default answer
        dd = wx.DirDialog(None, "Select directory to open", "~/", 0, (10, 10), wx.Size(400, 300))

        # This function returns the button pressed to close the dialog
        ret = dd.ShowModal()

        # Let's check if user clicked OK or pressed ENTER
        if ret == wx.ID_OK:
            wx.MessageBox('You selected: %s\n' % dd.GetPath(), 'Info',
            wx.OK | wx.ICON_INFORMATION)
        # The dialog is not in the screen anymore, but it's still in memory
        #for you to access it's values. remove it from there.
        dd.Destroy()
        return dd.GetPath()

    def ConfigFileCheck(self, evt):

        from ConfigParser import SafeConfigParser

        configfilename = "picportier.ini"

                pic_portier_working_folder = parser.get('picportier', 'working_folder')
        except IOError:
            if not os.path.isfile(configfile):

                except TypeError:
                    wx.MessageBox('Missing ini file', 'Info',
                    wx.OK | wx.ICON_INFORMATION)
                    sys.exit(0)
                f = open(configfile, 'w')
                f.write('[picportier]\nworking_folder = '+pic_portier_working_folder+'\\')
