You should have a look at the bedevere project:
http://bedevere.sf.net

It is a python wrap of gprolog using swig 1.1. I think you should be
able to adapt it to tcl. It works with gprolog 1.2.11.

If to choose to use bedevere, look at the sample code in the python
subdirectory: they are quiet explicit even if you don't know python.
