There are no tutorials on how to just make a layout. A layout should be your ideas. First worry about making it. Then people can teach you how to code it after its made. My suggestion get a program, photoshop, psp , or gimp. Then take your time and learn different things. Like blending, colorizing, simple effects, etc. Then create one of those into a layout.
But if you REALLY REALLY need to be told :
