The original guide should be some help but (warning: I haven't
looked at it lately -- if you get a better-informed comment please
disregard this one) I suspect it may not take into account the
fact that a fair amount of the API in early GTK+ 2 has since been
deprecated, and will disappear in GTK+ 3.

Since Ubuntu generally keeps pretty much up to date with GTK, you
should probably be looking towards GTK 3 compatibility. I'd
recommend referring to the old guide, but cross-checking this
against the html API doc for the current GTK release so as to
avoid substituting short-lived deprecated code for actually
obsolete code.

Your situation is a little awkward, since any current guide is
likely to focus on porting from (older) GTK 2 to GTK 3.
