Questions about creating an RSS reader

I am really green to开发者_JAVA技巧 this and came across this site by googling the subject. I am looking to create my own rss reader. I am wondering what language would be best to create a custom rss reader in the same lines as Google reader? I wonder what language do they use. Any and all help or direction pointing or suggestions would be greatly appreciated.

You need to be more specific

I have not used google reader but you can make an rss reader in any language, choose which best suits you.
