No, not in the sense that you can make arbitrary calls from arbitrary
threads to gtk functions and expect them not to crash.  But, if you
compile with -D_REENTRANT and libc6 (this is for Linux), you should be
able to use gtk from a threaded program without trouble as long as you
make sure that only one thread is ever inside gtk at a time.  This can
be accomplished (fairly well) with a big pthread_mutex around all
calls to gtk routines.  It may also be sufficient to just make all
your gtk calls from one thread.
