the functionality you want basically does not exist in GTK at this time.
there are ways to fake parts of it, and get things close to what you are
thinking of, but i would suggest revisiting your ideas about GUI design.
GTK is not the toolkit to use if transparency and so forth is critical
to what you want to do. Keep in mind, though, that transparency has only
recently been part of the "conceptual toolkit" for GUIs, and its
perfectly possible to design highly functional, deeply usable interfaces
without it.
