GUIs are a PITA like in most languages.

I think most people use something which binds to gtk (such as lablgtk) or Qt.

For scientific computing there is Owl, but I haven't used it personally.

Hmm, I'll stick with Python for now.

The ecosystem of libraries is just too good.

Perhaps if OCaml made it very easy to interoperate with Python, I could give it a chance.

There is pyml for interopt but I've never used it.
