Have you seen PostGIS < the GIS extension for PostgreSQL >
http://postgis.refractions.net

and the UMN mapserver
< it has a Python mapscript module and can map PostGIS data >
http://mapserver.gis.umn.edu

This will probably be much more responsive then using GMT in that
it renders using the GD library < .png files >  instead of going thru
postscript.

FWIW
Getting the above going within something like Quixote and using PIL
instead of the libGD is on my wish list ....

if and when I ever get a chance to work on it. :-(
