Welcome jesicapalma... to Java Forums.

If you are working on Netbeans it is much easy. You no need to worry about the design of GUI at all. I think it is ok for you.

As you said add three jTextFields and a button. To get the button event simply double-click on the button. You may comes with a method like this.

Code:

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
        // TODO add your handling code here:
    }

Then move to the functionality. Simply add following code segment in that method.

Code:

        int valueOne = Integer.parseInt(jTextField1.getText());
        int valueTwo = Integer.parseInt(jTextField2.getText());
        
        int sum = valueOne + valueTwo;
        
        jTextField3.setText(String.valueOf(sum));

Hope it is help to you.
