PIL uses the old-style Python license, which is considered to be GPL compatible
by the FSF (look for "License of Python 1.6a2 and earlier versions" in their list),
so mixing things shuold be perfectly okay.

If you build stuff on top of PIL that would be useful to other PIL users, outside
your application (e.g. file format drivers, new image processing algorithms, etc.),
it's of course nice to license those parts under a non-GPL license, but that's up
to you.
