Download FX Composer 2 from developer.nvidia.com. It comes with a program called Mental Mill that makes shader creation very easy. You don't need to know how to program. In fact don't even know if it has a code window come to  think of it. I've been playing around with the program the last few days and highly recommend checking it out.
