What are all good GUI & plotting package options for Maxima?

If I understand the question correctly, the concern is that if we
wished to tie the system very tightly to Maxima, thereby making
signficiant changes to the system, there are quite a number of things
we would have to worry about.  GPL or something more liberal works
fine, but the restrictions on gnuplot could cause problems if we want
to pull out pieces and integrate them.
