Yeah, it upsets a little.

As you said, you need cairo, as the graphic library, and a composite
manager as the windowing system. It could be hardware compositors as
XGL,or AIGLX, it could be software compositors, like xcompmngr.

You need to know how to make a gtk widget first if you want to
encapsulate this code.

You only need to paint to a cairo surface, you can learn in:
http://cairographics.org/samples/

very simple demo I love is http://plan99.net/~mike/blog/?p=38
and Macslow one:

there are very useful info in Macslow site.

I send you and example of  a widget with transparency.

Best regards
