I've come across the same problem and I don't know of an elegant
solution for it. Anyway, here's what I usually do:

You have code that actually makes the pop-up show up right? And that's
the code that needs access to the value in the JTextField, right? Well, the
pop-up itself is an object, right? So add a method in the pop-up class that
returns the value in the JTextField. The calling code then creates and shows
the pop up box as usual, and then waits for the "ok" button to be pressed.
It then calls the method you added to get the value that was in the
JTextField.
