I spoke to a bunch of people, and it looks like everyone uses either
QT or KDE.. there's not 'middle ground' where qt apps use a couple of
kde features.. So I think I'll just start with some of the libraries,
probably kdecore, kdeui, kio and kparts.

Right, my goal is to eventually have the entire kde api too (I already
have qt4).. But since Summer of Code needs something with actual
goals, I thought I'd start smaller (kde api is too big :(

For the plasma api, do you mean as an addition to the kde bindings, or
as a separate project? They don't seem to have an api defined yet, but
their roadmap suggests that one could start working on bindings at the
moment..
