Many years ago with my first c-10, I milled my own boards from mahogany, and refinished the metal strips in black, and it looked KILLER. I've never seen another like it before or since. I'd say it was fairly easy on the difficulty scale, but I was/am a professional cabinetmaker and had all the tools. (sure wish I could find an old photo).
My advice for the average guy that does not have a shop/tools/skills and wants an OAK bed.. Just buy it pre-made. WAY less headache and not that much more money. It'll fit right, look great, and take far less time.
Now if you want something unique or exotic, you may not have a choice but to do it yourself.
