Delphi – Rich GUI application in Delphi

I would like to create an application with rich UI elements and no VCL in Delphi (except a TForm). Each components (buttons, list, etc…) needs to support full per pixel alpha and be easily created without any codes. It should be skinnable and able to give result similar to adobe air application.

I've tried with GR32 (Graphics32), but each instance of TImage32 take too much memory.

Do you know any frameworks or components for Delphi 2009 that would allow me create a set of components for making rich UI application ?

Cheers!

EDIT :
The current alpha version of my application look like this :

I would like to have similar result but without using a TImage32 for each components (buttons, labels, panels, etc…)
