Ok, it's a bit unclear to me what that actually means :)
Is there some way to change the 'theme' from within the application?
or is that something that is defined in the XP os preferences somewhere and is 
not to be messed with, from my application?

It seems a bit strange that you would not be able to do what I am trying to 
do ?

I just want a differently colored panel, with a properly colored button ;)
