WxPython form not aligned

Hi everyone...

I'm building a small application that needs the user to enter a small form of data...

It's almost done except the fact that I can't get my input fields of equal width for every row...

What can I do to achieve that?

import wx
import  wx.calendar
from datetime import datetime



DATE_FORMAT = '%d-%m-%Y'

class MyForm(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, title='Pic Portier - Cosmonet', style = wx.DEFAULT_FRAME_STYLE & ~wx.MAXIMIZE_BOX ^ wx.RESIZE_BORDER)

        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.closeProgram, 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()

        # Add a panel so it looks correct on all platforms

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You'd typically use one of the grid sizers (either a flexgrid or gridbag).  If you want your top labels to line up with your bottom-- the labels above and below your calendar--  then I'd suggest a gridbag.  If you don't care, then you could go with two separate flexgrids.  

Here's a gridbag example:
import wx
import  wx.calendar
from datetime import datetime



DATE_FORMAT = '%d-%m-%Y'

class MyForm(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, title='Pic Portier - Cosmonet') #, style = wx.DEFAULT_FRAME_STYLE & ~wx.MAXIMIZE_BOX ^ wx.RESIZE_BORDER)

        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.closeProgram, 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()

        # Add a panel so it looks correct on all platforms
