In HippoCanvas we took this to the extreme of not including gdk.h or 
gtk.h in the canvas core. I happen to really like this approach, but in 
general I tend to like to keep code almost annoyingly 
layered/orthogonal, just a personal taste kind of thing that can create 
extra work.

Then as you mention there's an item that can contain GtkWidget and a 
GtkWidget that can contain an item.

It definitely has the downside that you'd have to replicate large parts 
of what's in gdk and gtk already. On the upside, if you're writing a new 
"widget core," apps could avoid the old one entirely someday. It's a 
"GTK 3.0 in parallel and interoperable with 2.x" sort of thing. Probably 
at least a little bit insane.
