ChatBox !!

Question

I'm working on my own project, it is just like our community where my native people can ask doubts!!

I also need to implement a chatbox (not chatbot), like Facebook !!

How to do that? Which language (s) I need to learn?

I already know JS, jQuery, HTML,css,PHP, SQL,Python and some system languages....!!

But still I'm struggling with the concept!!

Please guide me !!
