[SDL] GUI on sdl

[Bharat Singh GUSAIN]

hi all, 
i am new to sdl and is currently working on a webcam application developed in 
sdl for which i need some nice gui frontend.
mainly i need some buttons, radio groups, scroll bars, check boxes and drop 
down lists.
can anybody tell me that whether there is any library or calls in sdl, if not 
then how can i implement these features in my application.

Thanx in advance
Bharat
