High-level GUI libraries built on it

wxHaskell is a middle-level GUI library.^[2] Several experimental high-level GUI library approaches are implemented on wxHaskell:

• Reactive-banana
• FunctionalForms
• wxFruit
• Phooey

In contrast, the high-level GUI libraries FG and Grapefruit are implemented on the middle-level Gtk2Hs, which is based on GTK2.

All of these high-level libraries are experimental, using advanced mathematics concepts in their approach (see Arrow (computer science)).
