thanks. i'm on Windows though and slightly fascist and unreasonable in that i'm not particularly worried about the program working on another platform. i should have mentioned that though. (also i think if anyone needs a noob-oriented IDE, it's going to be Windows users)
i actually use Vim which is more than sufficient for my needs. what i'm thinking of making is a completely noob-oriented IDE, one where ideally the user does not even have to know about mzscheme this or arc3.tar that
Using mzscheme as some sort of high-level virtual machine isn't a bad idea as it may seem. In fact, I think that it could be quite practical even in the lon period. Speed is not blazingly fast, but it is quite good, and you get stability and a good portability without effort.
Some times ago I started a GTK+ binding, now "paused". It's more boring than I thought initially. If you wish look at it for a starting point (file gtk.arc in Anarki). I now think a binding towards tcl/tk would look nicer and easier to use, though.
