[guppi-list] Best Language for Guppi?

[linas linas org]

I need to implement some scripts/programs that will use guppi
for graphing live data being yanked out of shared memory
(as well as controlling a command-line system, and offering 
menu-driven GUI interface).  What's the 'best'/recommended 
language for quickly & easily implementing this (and still
having a very nice GUI finish to it?)

The choices seem to be 
perl-tk (is there perl for guppi ??)
scheme
C + glade for gui
python ( is there python for guppi??)
