Making windows stay always on top

[Newbie23]

Greetings!

I'm trying to make a little toolbar with some shortcuts to different programs that i often use. My plan was to set the opacity to around 50% and let the window always stay on top, however i don't know how to make a GUI/window to always stay on top... Here is an example that followed with autoit, hope anyone can edit it and show me how to make it always stay on top..

Thanks in advance

#include <GUIConstants.au3>

GUICreate("test",240,180)
$button1 = GUICtrlCreateButton ("1", 0,0,40,40,$BS_ICON)
GUICtrlSetImage (-1, "shell32.dll",5)
$button2 = GUICtrlCreateButton ("2", 40,00,40,40,$BS_ICON)
GUICtrlSetImage (-1, "shell32.dll",7)
$button3 = GUICtrlCreateButton ("3", 80,00,40,40,$BS_ICON)
GUICtrlSetImage (-1, "shell32.dll",22)
$button4 = GUICtrlCreateButton ("4", 120,0,40,40,$BS_ICON)
GUICtrlSetImage (-1, "shell32.dll",23)
$button5 = GUICtrlCreateButton ("5", 160,0,40,40,$BS_ICON)
GUICtrlSetImage (-1, "shell32.dll",32)
$buttonclose = GUICtrlCreateButton ("close", 200,0,40,40,$BS_ICON)
GUICtrlSetImage (-1, "shell32.dll",28)
GUISetState()

; Run the GUI until the dialog is closed
While 1
    $msg = GUIGetMsg() 
    If $msg = $GUI_EVENT_CLOSE Then ExitLoop
