GUI toolkit based on OpenVG or OpenGL ES

Dear All,
I’ve been working with OpenVG for a while and I really like it. Now I have to develop a GUI. I would like to use OpenVG. Could you possibly let me know:

  • What are good GUI toolkits based on OpenVG?
  • Is OpenVG a valid 2D rendering engine for GUI or should I look for something else, for ex. GUI toolkits based on OpenGL ES?
    Thank you very much.
