Red uses DSL's to make it pretty easy. It's a REBOL-like language that's easy to parse and macro kind of like LISP. Here's an early demo of how that looks with examples: http://www.red-lang.org/2016/03/060-red-gui-system.html http://www.red-lang.org/2016/03/060-red-gui-system.html I don't know Haskell but I know Galois does DSL's like Ivory language with it. So, I imagine doing something like Red's GUI in Haskell would be worth exploring. Alternatively, building such a clean abstraction on top of a cross-platform library with messy stuff generated automatically from DSL version.
