I will provide you with a ready-made Google, translator widget that you can easily integrate into your site.
You have to:
1) Let me know all the languages that you want to have your site translated on.
2) Copy and Paste the code that you will receive, onto every website page that you want to have a translation option.
Check out: http://deldot.gov for an example of a website translator.
