Recipes are just like any other beer. You make a Pale ale and instead of bottling or kegging, you cask it.
Cask conditioned beers actually are lightly carbonated at first. They are naturally conditioned in the cask like homebrewers naturally condition in the bottle. That carbonation dissipate quickly after tapping and no more gas is added as in a regular kegging system.
The beer engine you pour these beers with is just a pump. You can find them, but a quality one is a very expensive thing. It can cost as much as the rest of your setup...several hundred dollars. As far as a cask, I imagine you could use a stainless keg so it would be easy to clean.
Check ebay for engines. I've shopped around a bit, but the cost for good ones is scary.
Oh don't give me none more of that Old Janx Spirit
No, don't you give me none more of that Old Janx Spirit
For my head will fly, my tongue will lie, my eyes will fry and I may die
Won't you pour me one more of that sinful Old Janx Spirit
