How to Add LIKE button to Facebook APP?

[samak]

I made an app on facebook, but I am not able to get the "LIKE" button, seen here:

Notice how you see that LIKE button? HOW DO YOU DO THAT!?!?!??!?!?! YES I AM SHOUTING!
Whenever I try to make a page like that, I get a BLANK space instead of the "LIKE" button.

THANK YOU!
More examples of the "LIKE" button I am referring to:
