ruby

It's open source - i'm not sure what you mean by "can we write class in
class"

check out www.ruby-lang.org/en/about/

something that may be helpful for you to understand is that Ruby is the
language (created by Yukihiro "matz" Matsumoto - www.ruby-lang.org)
and that Rails is a web application framework (extracted from the
Basecamp project by David Heinemeier Hansson at 37 Signals) that
utilizes that language.

I, also, am quite new and would recommend the book "Agile Web
Development with Rails" -
http://www.pragmaticprogrammer.com/titles/rails/index.html - to help
you get started.
