Gnome Theme Creator

[Mihai Niculescu <q quark gmail com>]

Hello,

For some time I was looking for a gnome application to create Metacity, 
GTK and GDM themes, but I didn't find any. So, I decided to learn GTKmm 
(I have some previous experience with C++) and write an app that can do 
that. Basically, I want the application to be  entirely visual - 
something like  Stardock's SkinStudio for Windows: 
http://www.stardock.com/products/skinstudio/.

My problem is I don't know which way to take:
1 - to use a canvas with images to draw all widgets (Window, buttons, 
progress bar, tabs, etc...)
or
2 -  to use real widgets and modify their look using  their methods, for 
example:

modify_style(const Glib::RefPtr<RcStyle>& style)

3 - any suggestions you might have


Can you give me some directions, suggestions or comments?
