file extension based software execution

Hi Experts,
I am working in HP-UX 11.0 workstaion.
How can i make a file to be executed with the corresponding software to be invoked or executed.
as in Windows.
ie., if a file index.html has to be double clicked to invoke the Netscape Navigator.
What i have to do to achieve this task?

Regards,
