If it's just the choice of language that's the issue, try wmii. The default config is written in Bourne shell, but all of the actual interaction between the config and the wm is done through a plan9-style api, so you can configure it in any language you want. The Ubuntu package comes with sample configs written in Python and Ruby in addition to Bourne shell.
