I use a similar script for my IP camera network at home. I'm at the office at the moment, but something like this should get you started:
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <IE.au3>
#include <Misc.au3>
Local $oIE1 = _IECreateEmbedded()
Local $oIE2 = _IECreateEmbedded()
$myGUI = GUICreate("Deal A Day Sites", 1000, 500, Default, Default, $WS_OVERLAPPEDWINDOW + $WS_VISIBLE + $WS_CLIPSIBLINGS + $WS_CLIPCHILDREN)
$pic1 = GUICtrlCreateObj($oIE1, 10, 10, 400, 400)
$pic2 = GUICtrlCreateObj($oIE2, 500, 10, 400, 400)
_IENavigate($oIE1, "http://www.google.com")
_IENavigate($oIE2, "http://www.yahoo.com")
While 1
Local $msg = GUIGetMsg()
Select
Case $msg = $GUI_EVENT_CLOSE
Exit
EndSelect
WEnd
