What exactly do you mean by layout?

For a simple button and similar elements, just draw them into a texture and blit it onto the screen using the blit methods in FrameBuffer.

Onto a texture? Then this might help: http://www.jpct.net/forum2/index.php/topic,3794.0.html

(It's a rather long thread, but it should be possible to derive a solution from it.)

You can try to mix standard Android GUI/layout stuff with OpenGL output. Personally, I wouldn't do it, but that might be just a personal preference. If you do it that way, it's independent from jPCT-AE and this forum isn't the right place to ask for support.
The other option is stay within the OpenGL world, but that requires you to re-invent some stuff. For a simple button, you can create a texture that contains the button as an image and use one of the blit()-methods in FrameBuffer to draw it on screen.

Not sure what you mean? You want to combine the ImageSwitcher with Vuforia or what?
