GEM is a bit easier to deal with for shaders since there is no need to do any specific wrapper.  Any ARB_ vertex or fragment shader and any GLSL shader you find on the web can work in GEM without modification.  In some cases you might need to change something in the shader text to deal with rectangle vs 2D textures.
