Im using c# 2005 express edition

Ive pretty much finished an winforms application and i need to
significantly improve the  visual appeal of the interface.

Im totaly stuck on this and cant seem to work out how to start on a
solution.

I have of course used a varienty of componets, mostly radio buttons
with "button" appearence.

So i need a way to enhance the buttons and forms looks without redoing
or undoing  any exisitng coding, and i understand there are ways of
affecting the whole GUI and look of the application.

So where do i start with that. I would like to eventually be able to
customise the look of the whole range of visual componets, but in the
short term doing something like improve the look of the various button
and radio button and check button up and down visual states with some
sort of painted gradient to produce a metalic like look, even on the
back of the forms itself.

My internet research has not led to me to any specific step by step
examples on how i can do this.

It would be great if anyone could get me started with an example like
applying a gradient and bitmap  to a radio button while it is in
"button" appearence mode and adjusted for the up and down states
appearence,  in such a way as to affect all the same button types on
the forms, in the application

thanks for any help.

Im realy stuck on this one with no idea where to go from here.
