Will you allow users to create their own 'arrangers' ?

Could you create a system that allows users to create their own widgets 
out of simple 'building block' widgets?

How do you plan on supporting themes? Do you plan on allowing 'skinning?'

I'm also working on a GUI. My setup is like this...

Basic Widgets:
  - label
  - button
  - textfield
  - image

Can be recombined to create 'higher level' widgets, like a FileDialog.

skin.xml --> holds the images used to represent different widget 
functions (button, button_pressed, button_hover, etc.)

layout.xml --> holds a 'layout', a combination of widgets to create new 
widgets, like a filedialog

gui.xml --> holds all the layouts a single program will use, simple load 
it up with

GUI gui = new GUI("gui.xml");

and hook up signals like so...

gui.getLayout("filedialog").getWidget("btn1").connect(&guiobserver.watchButton1); 


Just some ideas.
