Add counter to social medias like twitter and google plus

Question

I'm not too familiar with the API of Twitter and Google Plus. Can someone put some light in my problem? I want to add a counter to my Twitter, Google Plus and Stumble Upon button. This will be integrated in my wordpress post and pages. I think already implemented the facebook button. My only remaining problem are, Twitter, Google Plus and Stumble Upon (optional).

Thank You!

You can use jQuery to get the counters...

I have a gist that does that for Facebook Pinterest and Twitter https://gist.github.com/andrefrd/9520512
