You don't have to with Windows GUI programming. The 'trick' is to do your
drawing onto a Pixmap control and then copy the Pixmap to the Window during the
w32HPaint event. The way to trigger that event is to call

  repaintFG(mywindow)

If you want to see how this is down you can explore the 'wordcatcher' demo
program that comes with win32lib.
