I think I'd design it a little differently, but of course ymmv. I would:

- pop up a dialog box to get the user's input

- once you've got their input you don't need the dialog box any more,
  so close it. You don't mention that the user can stop the long-running
  process so I assume that they can't stop it, which means you don't need
  the pop-up any more.

- start the background process (thread)

  - this displays a new window with the progress bar in it,

  - updates the progress bar while the process is running

  - closes the progress window when the process is complete

  - force the main screen to update

  - terminate the thread

If the user CAN stop the background process, I'd not bother with the 
dialog box, but just use a window containing:

 - the user input area
 - the progress bar
 - two JButtons, labelled 'Start' (inactive) and 'Quit' (active)

which would only vanish when the background process has ended. This 
arrangement lets the user quit at any time, but the Start button would 
only become active when the value has been entered.
