[plt-scheme] GUI builder ?

I agree. The great educational advantage of world.ss is this:

If you get the idea that the place you have to start is the careful
design of the data definition of World (the Model) and that you can
write the view and controller functions completely separately, you can
follow the design recipes and easily get really nice looking results. If
you fail to understand this you just get into a mess. That puts a great
premium on design and shows that abstraction and a systematic approach
pay off.

We should have world-gui.ss and world-web.ss to provide web and gui
interfaces that support the same sort of model view controller
abstraction. Anyone planning to write them? Anyone want to point us in
the right direction and we try to write them? gui.ss does not have the
same properties as world.ss
