Switching between multiple JPanels within a JFrame - swing

Question

http://imgur.com/VT3JHH8
This is what I am trying to create essentially to start my menu based game. I am wondering if my approach is good. I have created a frame class "SonomaRoller" shown below. In that class it adds "frame" my "panel1" as shown in the diagram. As of now I also have my images drawn in that class that appear as "panel2". I want the user to be able to switch between panels with the buttons in panel1. Some of the panels where panel 2 is will have buttons of their own as well. What is the best approach for this? Should i make seperate classes for the panels and add them in JFrame? Should I switch between panels using JFrame since it adds the first panel? I have included my code below for my two classes. I also have a Jtext pane below where the panels are.
Thanks in advance

Can you not use ActionListener to set the panel visible or invisible by pressing a button. For example:
panel_1Button.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
panel1.setVisible(false)
panel2.setVisible(true);
}
});
