JFrame monitor of a calculation

Who can tell me how the progress of a certain calculation can be shown in a JFrame?
I've made a JFrame, complete with a Panel & GridBag layout. Then the program begins a calculation (say, int x runs from 0 to 1,000,000 by means of a x++ loop).
On GridBag location [0,0] lives a JLabel that says "x = ".
Now I would like to see on location [0,1] my dapper int x grow ever larger until x = 1,000,000.
How should I go about that?

Swing doesn't do well with this; it would take a lot of work. If you have a long-running task and need to keep the user apprised of the progress you can use a JProgressBar.

Usually, updates come as a result of, or in response to user interaction. The app below shows this.
I agree. Here's the link:
