== wxHaskell ==
[[WxHaskell|wxHaskell]] is a portable and native GUI library for Haskell based on the wxWidgets Library.

Hello World example:

<haskell>
module Main where
import Graphics.UI.WX

main :: IO ()
main
  = start hello

hello :: IO ()
hello
  = do f    <- frame    [text := "Hello!"]
       quit <- button f [text := "Quit", on command := close f]
       set f [layout := widget quit]
</haskell>

This code was taken from [[WxHaskell/Quick_start | "a quick start with wxHaskell"]].

== Gtk2Hs ==
[http://haskell.org/gtk2hs/screenshots/ Gtk2Hs] is a GUI Library for
Haskell based on GTK. [http://home.telfort.nl/sp969709/gtk2hs/ Gtk2Hs Tutorial].

Hello world example:

<haskell>
import Graphics.UI.Gtk

main :: IO ()
main = do
    initGUI
    w <- windowNew
    b <- buttonNew
    set b [buttonLabel := "Quit"]
    onClicked b $ widgetDestroy w
    set w [windowTitle := "Hello", containerBorderWidth := 10]
    containerAdd w b
    onDestroy w mainQuit
    widgetShowAll w
    mainGUI
</haskell>
