An adequate answer to your question would basically look like an introduction to the Rails framework: the MVC structure, templating, and routing DSL at least. Jeff has given a good stab, but his answer still assumes a lot of basic Rails knowledge on your part.
I'd suggest though, that if your webapp is really that simple, Rails might be overkill. I'd look into something lighter, like Sinatra, which has a much lower learning curve than Rails and does a great job of this kind of thing without having to deal with complex routing, magic MVC action/template mapping, etc.
