Try Jaybees Amiga in a Box at:
http://aiab.emuunlim.com/His installation comes with WHDLOAD already installed and configured. I also use Cloanto's Amiga Forever Online Edition (reasonably priced and they are definitely an organisation worth supporting).
By the way, at risk of stirring the debate, I am ashamed to state that sadly, I have absolutely no problems running WINUAE, or any Windoze games on my Windows XP. I can't even get Game Commander to freeze fer X's sake....
