If you want to simulate a mouse-click in Windows, I recommend using the mouse_event() function, specifying the MOUSEEVENTF_ABSOLUTE and MOUSEEVENTF_LEFTDOWN flags. However, I think you need to move the cursor to that position before you simulate the click, so you should throw in a SetCursorPos() function, just to be safe:

int coordX, coordY;

// sets the mouse's position
SetCursorPos(coordX, coordY);

// simulates the click
mouse_event(MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_LEFTDOWN, (DWORD) coordX, (DWORD) coordY, 0, 0);
// use a pause, if you wish
mouse_event(MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_LEFTUP,      (DWORD) coordX, (DWORD) coordY, 0, 0);


While I realize you said don't print MSDN pages, there are parameters of the mouse_event() function that I didn't use, and you may wish to, so here are the pages to the functions I used:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/userinput/mouseinput/mouseinputreference/mouseinputfunctions/mouse_event.asp
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/resources/cursors/cursorreference/cursorfunctions/setcursorpos.asp

This should do the trick, although some may also recommend the SendInput() function, but trust me, the mouse_event() function works fine for me.
