Have you looked at Quantum GIS (http://qgis.org) ? It's a desktop GIS
that can be used to visualise vector data from PostGIS as well as
shapefiles, GeoTIFFs, and other vector and raster formats supported by
the OGR and GDAL libraries. It's written in C++ using Qt though, not
Perl and Tk, but it should fit all your other conditions. If you want to
replace the backend it's pretty easy to write a new "data provider
plugin" that lets QGIS read a new vector format, and if you want to
expand the GUI it's pretty easy to write plugins for that too.
