If you value your sanity, put the XUL handbook down and step away slowly. Of the handful of completely failed software projects I've worked on, most have involved XUL and the Mozilla runtime stack in some major way.
The complexity of XUL isn't worth it for the payoff, IMHO. Stick with something simple like Shoes or Tk, or go for Qt or WxWindows if you need a rich widget set. Don't let the fact that XUL looks kind of like HTML mislead you into thinking it'll be easy to build on and deploy.
