I'm giving Titanium a go: <a href="http://www.appcelerator.com/" rel="nofollow">http://www.appcelerator.com/</a> . It's basically a wrapper for Webkit, so you write in HTML and JS (with extensions) and can also include Pyhton, Ruby, and PHP. Titanium then compiles your wares to Windows, OSX, Android, and iPhone.<p>Very neat.
