You could probably embed/nest ML quite conveniently under another framework and
do some fun GTK stuff. You could also make system calls to the ML prompt and
play with the output, I guess. My experience with Qt is more limited, so I
don't know if this can be conveniently achieved (more confined). Trolltech
made some nice IDE (what would Nokia do to it, I wonder?) and I didn't know
about Glade when I worked with GTK. MATLAB is the same in the sense that you
could do all the UNIXy stuff usign system() calls. I've always made my
programs Linux-oriented. Anything else was treated as 'other'.
Does ML for Windows run as a standalone program? Or is the dreadful cmd.exe
needed (it's quite ugly and lacks function)? I never tried it.
