Well, it really depends on what you want this window to do. The most basic Windows program that creates a dialog box would just be something like this:
Code:
#include <windows.h>
int WINAPI WinMain(HINSTANCE hInst, HINSTANCE hPrev, PSTR szCmd, int iShow){
MessageBox(NULL, "Hello, World!", "Simple Dialog", MB_OK);
}
If you want to do more complicated stuff, email/PM me and I can hook you up with some examples. Also, take a look at RoboGUI, which you can find at
www.robbayer.com, as it contains a bunch of Windows code. If you're interseted in MFC, take a look at RoboEmu too.
