simpler example of embedding in wx

I'd like to offer a simplest possible example for embedding in
wxPython; significantly simpler and completely pared down compared to
either of the two that are shown here:

http://www.scipy.org/Matplotlib_figure_in_a_wx_panel

but I don't have access to modify the page. Doesn't anyone on the
list have that access, and
would that be welcome? My example is ~20 lines long.

Thanks,
Che
