how to get kannada on form items like a button ?

Question

i want to develop an application which processes bank activities(Banking App, say. for rural small bank). I want the display on form tools(label,button etc) to be displayed in kannada language so that rural people will learn using it quickly. 

I want to use PHP and MySQL.

So how I need to proceed?  Is there any dll file i can get to do the same?

If there are dll's for any other language also please tell me.

thanx in advance
