Oh my, of course there is a porting guide:
   http://developer.gnome.org/gtk3/3.2/gtk-migrating-2-to-3.html

Sorry for the confusion, you should really be posting to a GTK+
list (gtk-list or gtk-app-devel-list) for issues you have with
porting your GTK+ app (you will get a faster response there because
you are on topic and there are much more users).

This list is more about using the Glade tool, but I'm happy to answer
your questions when I have time.

Cheers,
    -Tristan
