I think you are getting confused between learning programming and learning technology and language. I will say start with one language and learn programming first. Once you learn programming than you should be able to code in any other language once you master the concepts. using javascript you mainly deal with web client side programming, where as when you say java app it deals with so many (desktop, server side etc). You can download microsoft visual express developer edition and start learning C#. Which will give you all aspects of development. leaning any open source is much harder even though you have tons of documentation available all over the web
