I did this about a year ago, and I've learned recently that there are some much better techniques that are almost as simple (i.e., 1-5 external components per sensing channel). CapToolKit is a good start: http://www.capsense.org/
Thank you for info. Beside CapToolKit, STM's open source cap. sensing library and freescale proximity sensing software would be also good starting points.
