Turning comments into hyperlinks

[Sohail Somani]

Greetings Earthlings!

I have come across an inconvenience which I would like to resolve. I am 
working on a codebase which has the following patterns throughout the code:

// JIRA 12312
// ISSUE 12312
// KEY-12312

What I would like to do is match these patterns and turn them into 
hyperlinks that open in the browser. So for example, I might turn 
KEY-12312 into a hyperlink to http://jira.myhomies.com/KEY-12312 but 
continue to display the original text.

How would I accomplish this with cc-mode or emacs in general?

Thanks,

Sohail
