Well you load the bitmap, you draw it on the dc of the window then you parse the dc and for any point of the transparent color you create a window region. You add   these regions into a destination region then you substract this destination region form the window region and set the resulting region as the new window region. That should do it.

For more help look at the followin functions in MSDN or other MFC documentation:

LoadImage                           //win32 API
CDC::DrawState                      //MFC
CDC::GetPixel                       //MFC
CWnd::Get/SetWindowRgn              //MFC
CombineRgn                          //win32 API
CreateRectRgn                       //win32 API
