 Yes, you could do this with wxDC but try doing it with wxWindow (which you
don't just use as a local variable but have to use as child/parent of other
windows).

 You didn't reply to this but the above is really my main concern with your
proposal. You may have the best intentions in the world but without being
able to show a working wx3 program any time soon, we'd have a very hard
time going anywhere with it.
