TCL/TK is being used in many applications, including GRASS.  Any
application that can be used on the command line or a script can easily
be implemented.  

GRASS has some oddities 
	(see Re:redirecting standard error - yesterday)
but I have made a basic vis tool for several specific applications.
It is also amenable for use in integrating GRASS to database 
applications.  In particilar, I made a specific tool that uses
INFORMIX directly and GRASS for spatial queries.

Of course this could be done on the C level as the inf tools
but I would not know about C....

If you are serious about TCL/TK you may want the manual though...
