Hi,
I'm not entirley confident that using GtkStyle[1] is enough. You will  
have the option of copying and pasting the drawing code from gtk  
(e.g. _gtk_button_paint to paint a button) or to allocate a native  
widget (e.g. GtkButton).

The RenderTheme code is almost self explanatory and there are at  
least three complete examples. If you are interested in implementing  
it join the #webkit channel on irc and there are at least two of us  
interested in the Gdk/Gtk port. This would greatly reduce the  
roundtrip time.
