I've been playing around with GTK and Falcon (via gtk-server - seems
better on Windows that the Falcon bindings).
I've come up with an editor - written in Falcon, of course. Still
primitive, but usable. It also has buttons
to run Falcon code, indent it, do a cross-reference, and warn for
some possible mis-uses. Runs on Windows.
There is something about writing it in Falcon. It feels satisfying -
I guess it will have advantages I have not yet thought about
(embedding, etc...)
I think it would run on Linux easily - I discuss this on the site
below.
