Urdu Language Support

Hi,

I am trying to use google trasliteration service (English ---->Urdu) on my Apple Macbook PC (10.5 Leopard) with Word (Office:Mac) software.

I tried (English ---> Urdu) transliteration service on the website "http://www.google.com/transliterate/#" using my MAC machine keyboard and it worked fine. But when I download the API to use the same service on my machine (Apple Macbook, which BTW worked fine on MS XP pro machine using MS word) I do not know how to configure the language and enable this service. Please help me out.
