What language?

The exact implementation will depend on what language you use, but here's the general idea:
1) When "start" button is pushed get and save the system time.
2) In your "clock display" display the time difference between now and when you push "start".
3) Repeat step #2 until the "stop" button is pushed.

Let me know if this doesn't answer your question.

Sorry my mistake

I'm coding in Cocoa, Objective-C with Xcode. If you have anymore advice please tell.

Here is Apple's developer documentation on the NSTimer object. You'll probably want to make use of NSTimer so you can update the time elapsed in your program's window.

I'm sure if you do a google on NSTimer example you'll find some sample code that'll set you on your way.
