Why did FRP not work for you? You could try reactive-banana[1], which has
specific support for GUI. If you want something closer to MVP,
binding-gtk[2][3] might help.

If you post more details about your application, someone may be able to
suggest a better way of structuring it. MVP originates from OO, and
OO-centric patterns are usually not the best way to go about something in
Haskell.
