You're on the right track, but you're creating the frame's inside the loop, not outside. Here's what it should be like:

private void printWords() {
    JFrame frame = new JFrame("Run Text File"); 
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
    JLabel textLabel = new JLabel("", SwingConstants.CENTER);
    textLabel.setPreferredSize(new Dimension(300, 100)); 
    frame.getContentPane().add(textLabel, BorderLayout.CENTER);
    //Display the window. frame.setLocationRelativeTo(null); 
    frame.pack(); 
    frame.setVisible(true);

    for (int i = 0; i < words.size(); i++) {
        //How many words?
        //System.out.print(words.size());
        //print each word on a new line...
        Word w = words.get(i);
        System.out.println(w.name);

        //pause between each word.
        try{
            Thread.sleep(500);
        } 
        catch(InterruptedException e){
            e.printStackTrace();
        }
        textLabel.setTest(w.name);
    }
}
