I'm trying out a simple gui. I'm trying to create an text area to allow me

JTextArea will do the job, but I'm having problems making it appear.
The code to add to my container is
Container contentPane = frame.getContentPane();
JTextArea itemArea = new JTextArea();
contentPane.add(itemArea);
is the contentPane the main area of the window ?

Post the complete source code to I understand what you are doing with
frame reference.

Look a simple working source code:

-------------------------------------------------------------
package javaapplication3;

import javax.swing.JFrame;
import javax.swing.JTextArea;

public class Main extends JFrame {
private JTextArea textArea;

public Main() {
super("PH");

setSize(500,500);
setVisible(true);

textArea = new JTextArea();
getContentPane().add(textArea);


Forgive me. Put

setVisible(true);

after the

getContentPane().add(textArea);

Maybe, this is your source code problem too.


}

public static void main(String[] args) {
Main application = new Main();
application.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

}
