I would write a shell script using the GRASS's g.parser[*]. Adding that
to the GUI in GRASS or in QGIS would be easy to do - just keep the logic
out of the GUI, use it as a front-end.

[*] see the included GRASS 6 scripts/ in the source distribution and
  http://grass.ibiblio.org/grass60/manuals/html60_user/g.parser.html
 for ideas.
