I assume, that you use a separate thread for this. But Swing is (mostly)
single-threaded.
That means, JComponents should only be manipulated from the AWT Eventqueue.

The right way (tm) is to put every modification from another Thread
into the AWT Eventqueue. Fortunately, there is a helper for this:
SwingUtilities.invokeLater(new Runnable() {
public void run() {
tfCount.setText(...);
}
});
That should do it.
