There are several web applications for GRASS available:
http://www.geog.uni-hannover.de/grass/index2.html
-> Links and Screenshots

The port to windows is on the way and will include the tcltk-interface.
A preliminary version shall be checked into CVS on Tuesday which
makes the GRASS monitor running on Cygnus/Win-NT. You must distinguish
between the menu system and the graphical output. Latter is pretty difficult
to port to Windows.

Kind regards
