Another free CAD program for pcb making is designspark pcb (http://www.rs-online.com/designspark/electronics/eng/page/de...). It's not opensource like Kicad and gEDA, and it's only available on Windows. But it's easy to learn, very polished for free software, and quite capable. Lots of tutorials as well. There is a lot of free software available for hobbyists/makers today and they're pretty impressive compared to commercial software.
