Easy: draw a rectangle encompassing all the controls you want "grouped", give it
a border and/or a distinctive background color, all this using drawRectangle().
Then create a label with appropriate background and text, sticking it where it
seems more relevant or viible. This way, the frame work will simply be a visual
frame. Oh, and setEnable(the_label,w32False) so that it doesn't interfere with
tabbing.
