even with a shader editor you still need knowledge(sure you can click together different parts like adding reflections and toon, or what is offered in the editors base, but...). taking rendermonkey for example if you dont know what you are doing you will get as much errors as using a texteditor and 3dgs;-)
keep on trying, get some books (realtime shader programming, shaderX) and look into the dx8 sdk (or dx9) and try the search engine there.
