Dialog that returns an Object

Is it possible to create a JDialog in swing that would return an object when OK button is clicked?

For example the Dialog box has text fields that have components that make up an adress ( street name, country etc.)

When the OK button is clicked an Address object is returned.

Why I thought this to be possible was because of this. But what I want is something like I mentioned above.

Any pointers on how to get this done would be very helpful.
