You can set the bg color of the button to be the same as the panel, but 
that would probably not be much better.  You can use a generic control 
instead of the native button.  Or you could try removing the manifest 
from the app so the old unthemed controls are used.

Keep in mind that on Windows the button, notebook and other controls are 
all separate, mostly independent window objects, with their own 
background, foreground and paint event handlers.  Add to that the fact 
that the new themed controls toss out a lot of the old rules for the old 
style solid color controls, and draw themselves with textures, 
gradients, or images.  So the old concepts of setting a fg or bg color, 
or inheriting it from a parent don't mean much anymore, at least for 
some widgets.
