Writing a plug-in for the GIMP does not do anything
prohibited by copyright. Even if you include header
files and such, that comes under "there's just one
way to do it", which makes it OK. So you don't need
permission and you don't need to distribute it under
any particular license.

Some GPL theorists would like it if making a program
that inter-operates at the code level with another
program would entangle its source in the copyrights
of that program, but in fact that does not happen.
