Simple wxWidgets test program (with source)

Luckily for us, audacity is open source, so we can find out what it's doing.
The problem seems to be with wxWidgets, to be specific, with wxEXPAND.

While I don't have a fix (or even a hack) yet, I managed to create a small test
program using only wxWidgets, which I'm attaching. This should make debugging
easier, I hope it's useful. If you want to take this on, be my guest, if not,
then I might look into it.
