I do want to do this in Glade. (Though to be honest I had been mainly thinking
about C.)

We did allow extra widget properties for other languages, e.g. C++.
What other features would be useful for C++?

I've had similar problems developing Glade, since GUI builders work best
with an object-oriented approach, i.e. widgets + properties. GtkToolbar
was quite awkward, and so was the Gnome stock stuff.
Since Glade converts the interface into a fairly OO XML file, I would
have thought that turning this into C++ wan't that bad. Though I suppose
there may be a mismatch in the way we have split things into 'objects'.
