I am far from a DIY guy, so I can't help with the design, per se. BUT... where you said you wanted to use wood, maybe you want to look into PVC boards, which look nice, don't need sealing, and are fairly easy to work with. Not sure if it's easy for you to find them in your local area, or cost. Here in NY, Home Depot and Lowes carries it. And, a 8x4 sheet, 1/2 inch, is about $50.
Yea thats alot more than i wanted to spend. No more than id need. Hmmm
