    There is nothing wrong with using gdk in conjunction with gtk,
GtkWindow is a GtkWidget, and (as seen in your code snippet) every
GtkWidget has a (GdkWindow *)GTK_WIDGET(wid)->window (unless ofcourse
it is GTK_NO_WINDOW).

So the code doesn't work you say ?, maybe all expose events need to
be handled before calling gdk_window_end_paint(), you could accomplish
this with either:
 A.)
    while (gtk_events_pending())
          gtk_main_itteration_do(FALSE);

 or probably:
 B.)
    gdk_window_process_all_updates();
    (not sure about this one ...)

Good luck, and please let me know if it worked ;-)
