Follow me widget in right side bar

Hi guys

I´d like to include a widget like the one you use in your blog´s right side bar. the one that shows how many followers you have and also shows the friend face and a like button.

I´ve gone though the fb like button code generator here
https://developers.facebook.com/docs/plugins/like-button

I provided the fb fan page url and got the code. after that I inserted a text widget and use the fb code as html5 and iframe but nothing happend!!

some help please.
