Your 'a meets b' explanation really explains your game perfectly. Typically with nothing to show, explanations can be a bit hazy, but it comes across perfectly. So I'd suggest you take that as far as possible; call it "a to b" and put an 'A' and 'B' on each ball.
Is that sarcastic ??

I am sorry, I am still at a very very initial stage of development wont have anything to show for around 2 weeks

Those Facebook pages are very outdated. The REST API was deprecated a year ago, use the GRAPH API now.
Just get your game to run in an applet and use the iframe method.
I found the JS and PHP lib easier to work with than the Java ones.
The widest you can make the applet is 760px, height is unlimited.
Hope that helps.
Hey thanks .. I'll look into that as well =)
