Animation with GTK+

["Prokopenko, Konstantyn" <kprokopenko ezem com>]

Hello,

I'm totally new to the GUI application development in Linux X11. I was
mostly involved in embedded non-graphical development.
Now I need to create GUI interface application using GTK+. 
Could you advise me the best way to create animation of a rotating
object in GTK window? This object is going to be a picture of a device
rotating in sync with a real hardware device. Which library/extension I
can use?

Thank you.

Regards,
Konstantyn
