Rating and Comment system

I was wondering how to create a list (or table) with items for my website where users can click any of the items, rate it and comment on it, then create an average of all the votes and see all the comments every time they click in the items.

I've been googling for days but can't find anything related about it.

Here's a picture of something very similar.

(sarcastically) Oh, 'a server-side scripting language'. Oh, I say, we are grand, aren't we? (imitation posh accent) 'Oh, oh, no more buttered scones for me, mater. I'm off to play the grand piano'. 'Pardon me while I fly my server-side scripting language.' Now get on the table!

Server-side scripting language eh?
