Hi Peter,
  Thanks a lot! I will try to test this weekend when I come back home on my
own computer under UBUNTU. Actually I think you are right, for when I test
on my another loptap which the OS environment is WindowsXP, it popuped two
window when I launch my program, the fisrt is a command line window, the
second is the GUI window. After I close the command line window, the whole
program stop. And the below is my test code:

import Graphics.UI.Gtk

main :: IO ()
main = do
  initGUI
  window <- windowNew
  set window [windowTitle := "Pix", containerBorderWidth := 10]
  button <- buttonNew
  onClicked button (showWindow)
  containerAdd window button
  widgetShowAll window
  onDestroy window mainQuit
  mainGUI

showWindow :: IO()
showWindow = do
  initGUI

  window <- windowNew

  widgetShowAll window
  onDestroy window mainQuit
  mainGU
