I'm not too sure you do need the SDK if I'm honest, though the documentation does say you do, my guess is it does some rendering on the xfbml. It also means you can add in callback functions.
The other thing you will need is the OG tags on the page so it renders correctly.
I'm guessing you've seen this page?
