Is it possible to have a mesh coloured and textured in cycles and then have it displayed in internal?

The only reason I ask is because I am building a log cabin and want to put some windows in. When I have done glass in cycles (Nodes) it looks much better (realistic) but when I try to do this and go back into blender internal to finish the rest of the log cabin off the window and the mesh surrounding the window becomes undefined and discoloured.

Is this because I am trying to put cycles into internal or because I am doing something wrong?
