use Google Translation API
http://code.google.com/apis/ajaxlanguage/documentation/#Translation
you can try that here
http://code.google.com/apis/ajax/playground/#translate
In that editor, you can change the source text and translate that to hindi using
google.language.translate(text,
'es', 'hi', function(result)
{
Then you should be able to see
Hola, me alegro mucho de verte.
हैलो, मैं तुम्हें देख कर खुश हूँ.
you can add the script reference in your page and use that API.
