Gnome desktop wallpaper changer

[Sumit Chakraborty <cool sumitc gmail com>]

Hi
I want to create an application that fetches wallpapers from websites like gnome-look.org, deviantart.com et al and sets the wallpapers as desktop background. I want this application to be integrated into the gnome control center. 

Can anyone guide me so that the project sees daylight? 
Any idea/collaboration/criticisms are most welcome.

Regards
