Multi video call site [on hold]

So guys ,I'm thinking to build a website with multivideo calling site. My problem is that I don't know which language to use or which script language to use.

Just to give you an overall idea:

I want my site to be like a poker site and in the table instead of photographs or avatars to see the opponent live from a camera broadcasting.

So guys any ideas which tools or languages to use for building this kind of a website ? I am not a professional programmer or web developer so anything will be helpful for me.

Thank u in advance guys!
