Rob,
No, there is no support to do this. You would have to override the
WndProc method of your class and handle the WM_NCPAINT message, which is
sent to paint the frame of the form.
As for getting the default button, that's going to be hard. You could
use the visual styles api, but it doesn't have anything for an "empty"
button. Rather, you can paint a different button (max, min, etc, etc), and
then just paint inside of it.
Hope this helps.
