Opening a JTextArea when a button is clicked

I'm writing a program that contains many buttons and when I click one of them, I want it to open a JTextArea with some txt file info in it. I tried to add the JTextArea to the button but it didn't open anything. I'm new in Java so I don't know if this is the correct approach to take.

I defined the button and JTextArea in the GUI

showListButton.add(jTextArea);

And here is the code I wrote inside of public void actionPerformed(ActionEvent e)

if(e.getSource() == showListButton){



          try {
                BufferedReader in = new BufferedReader(new FileReader("file.txt"));
                String word;
                while((word= in.readLine()) != null)
                {
                     jTextArea.read( in, null );
                     jTextTextArea.requestFocus();

                }
                in.close();
            }catch(IOException e1){
                e1.printStackTrace();
            }

        }

To display something you need a root container like a Window or a Jframe. To display your textarea you have add it in another frame that you will display on click or add it an already displayed panel.
