Rajeev, one more alternative is to use Google Translate API. 

https://developers.google.com/translate/v2/getting_started

Here, you get support for many languages. But It charges $20 for each 1 Million characters to Translate/Detect your text language. It may reduces your headache of duplicate entry of data in database/resource files for different languages.

I think, you should have Hindi typing skills for this. Use this link to download hindi font.

You can also choose another one simply search for "Hindi Fonts" in google. 

Once you install them in your machine. You'll be able to use it immediately.

For a website, note that not all your clients' machines have this font installed. So they can have difficulties to read your web page. To get rid from this. The use of 'font-face' is recommended in CSS.
