Yes, in a sense -- most of the tkobjc/ module and some of the
simtoolsgui/ module.  Essentially the API is just an Objective C
veneer for a subset of Tk.  Get a book on Tcl/Tk and then pass
commands to [globalTkInterp eval:] in Swarm, from #import
<tkobjc/global.h>.  You'll probably find that you can do a lot with
what is in gui.h, without doing raw eval: calls.  I'd be happy to tweak
the gui.h APIs if you are interested in working on something of more
general utility than your models...

Sure, you could do that.  I get the impression you aren't inclined to
use Java?  If you want to do something new and shiny instead of old
and crufty, maybe you'd like to try some XBL/XUL programming in
Mozilla??  ;-)

Btw, a good project for a volunteer would be to make ProbeDisplays
show CheckButton for booleans.  That assumes a tolerance for Java, though,
since BOOLs in Objective C are not something preserved by reflection.
