Haskell Graphics Library that works in GHCi on MacOS X

Question

Does there exist a Haskell graphics library or binding to an external library that fulfills the following requirements:

1. Can be used from ghci, i.e. I

Answer 1

The Gtk2Hs library fulfills all the requirements if you use the X11 version of the gtk2 framework.

Concerning the requirements:

1. Using X11 avoids many problems.
2. Install gtk2 via MacPorts and use the +x11 option (default). (That said, I've had numerous problems installing gtk2 in the past, but this time it seemed to work.)
3. I would be surprised if GTK+ can't do that.
4. Ditto.

Here a minimal example

import Graphics.UI.Gtk

hello :: (ButtonClass o) => o -> IO ()
hello b = set b [buttonLabel := "Hello World"]

main :: IO ()
main = do
    initGUI
    window <- windowNew
    button <- buttonNew
    set window [windowDefaultWidth := 200, windowDefaultHeight := 200,
              containerChild := button, containerBorderWidth := 10]
    onClicked button (hello button)
    onDestroy window mainQuit
    widgetShowAll window
    mainGUI
