I've gotten this to work with Perl 5.8, and I just (5 minutes ago) finished a basic Cairo/Glib/Gtk2 Perl stack for Perl 5.10.0.
The order of building is Perl, Cairo, Glib, and then Gtk2. My notes from this latest build are posted here:
It's 4 pages in sequence (follow the links at the bottom of the page to navigate). I have not updated the "Extra GTK Apps" page yet, but I don't expect any surprises. I don't know where you're at in your build (sounds like you got Cairo and Glib working, but not Gtk2), so maybe this will help you. If you do use my notes, at the very minimum, you'll have to change anything with a path of C:\camelbox to C:\strawberry, but I think that's about all you would need to do. For your Windows GTK libraries, are you also getting all of the support libraries that the GTK libraries are compiled against? The GTK libraries I used are on this page:
I have all of the Binaries/dev packages under the GTK+ section, as well as all of the "Third Party Dependencies" that are marked with a checkbox image on the right hand side of that table.
I don't even bother with running the tests, I'm on the gtk-perl mailing list and the developers have acknowledged that the tests *will* fail under Windows. But I can still get a working and current Gtk2-Perl stack on Windows, so I'm happy.
PM/post here if you need any pointers.
P.S. My demo app (outside of the Gtk2-Perl demos that come with the Gtk2-Perl source):
