Here's an idea

XML/YAML based GUI Element Description Language

Using this language, all we need is a blank canvas to render the GUI
Elements/widgets to.

Something like

<guiElement name='button'>

   <create>
       <cstr>
           <parm name='name'>
                <setVariable name='name'>
           </parm>
           <parm name='x'>
           </parm>
       </cstr>
   </create>

  <render>
    <box>
       <x><variable name='x'/></x>
       <y><variable name='y'/></x>
       <w>100</w>
       <h>100</h>
    </box>
    <shade>
    </shade> 
    <font face='Arial' size='10'/>
    <text><variable name='label'/></text>    
  </render>
 
   <events>
   <events> 

</button>

Plenty of oportunity to cache rendered bitmaps for efficiency.
