title: Best lightweight, responsive GUI framework Linux
body: <p>I've bought a Raspberry Pi, featuring a 300 Mhz CPU, but it does has a pretty good GPU. It can even run XBMC. I want to program a GUI for it, which needs to be responsive and good-looking, while taking optimal use of the hardware available (which isn't too good, unfortunately..). The Raspberry Pi runs Debian minimal, and I've put the X Windowing System on it, the rest is up to me to code.</p>
  
  <p>What is the best way to dive into this? I've already looked into HTML5 and jQuery (via Python and PyWebkit), but they seem to be too CPU-intensive (unless someone knows how to get (Py)WebKit use the GPU, instead of the CPU).</p>
  
  <p>To avoid confusion, this system will be hooked up to televisions and the like, and will be primarily pointed on home entertainment. I don't want this to be a desktop or desktop-like system, I'd just like to know what you guys think would work smooth on the Raspberry Pi box, so that I can program my UI upon that framework.</p>
