How to use Swing Worker

Question

Hello,
I have an exe file which is to be called from my program and it runs as seperate thread. The main purpose of this exe file is to create two files within the application directory. Next my program check to see if these files exists if these file exists then the program display that the files have been created to the user..
Now my problems
The part of program which checks to see if the exe has created the file should runs in while loop as a seperate thread.
The part of program which displays that the file is being generated should also runs as another thread.
Please any body could code/pseudo-code the above for me, I would really be thank full and appreciate. I have tried to do the above, but in vain because some times the GUI interface does not get updated or some times the file does get created and the program loops forever.
Please help
Josh

I just use SwingUtilities.invokeLater(..). Something like:
SwingUtilities.invokeLater(new Runnable()
     public void run()
          someTextField.setText("some new text");
});
