It should be (and I assume it's what kGtk does, but I haven't looked yet) be
as simple as providing a kde library that contains functions of the same
name as the gtk library functions.  The trick is to make them get called
before the gtk functions _only_ when your desktop is KDE (no doubt
_someone_ would find another use case, but geeks can take it from
there...).
