... and respectively for GRASS:
- how to start it:
  http://grass.osgeo.org/grass64/manuals/html64_user/helptext.html

- Geonames.org import (into lat-long location):
  http://grass.osgeo.org/grass64/manuals/html64_user/v.in.geonames.html

- Distance matrix (use "Print output" there)
  http://grass.osgeo.org/grass64/manuals/html64_user/v.distance.html
  -> Examples, Print distance matrix
      (in lat-long, it calculates them as geodesic distances on a sphere)

cheers
