I think that yo should start with C,many of the programming courses in both universities and highschools try to teach this programming language first, mainly because is very easy to read and understand... After learning the basics you could start with some ruby on rails beacuase you could be able to develop powerful applcations in less time... Good luck! ;)

With the right guidance, perhaps, but probably not on their own. It helps that JavaScript has C-style syntax, but a beginner would not know which features to avoid (http://oreilly.com/javascript/excerpts/javascript-good-parts...).

you should start with ruby!

Ruby on Rails (RoR) is very good
