XF 1.5 Follow a posters Twitter account?

Title is worded badly.

Basically, I want to make a field where a user adds there twitter (which already exists) but I want to make a twitter follow button for that user below/on threads/posts he makes.

I want to be able to allow users to gain a following though my forum. Is there an easy way to do this or more custom?


P.S. Any other social media stuff, say there facebook page or something could be good too, but focusing on twitter for now.
