Swing GUI for WebRTC

Dear all,

I have just started to learn WebRTC, I am going to develop a java desktop
application based on Swing API that communicates with other side using
WebRTC protocol, something like Yahoo Messenger.
But, as far as I understood so far about WebRTC, this is not possible
because WebRTC is bounded to browsers and mobile applications. Is it
possible to use java swing api to develop a desktop application without
using javascript?

Best regards,
Karimi
