Help: Displaying Images AND Adding Buttons

At first I had no idea how to display images in a window displayer, so I browsed through the web to find some code, and ended up with:
http://download.oracle.com/javase/tu...dImageApp.java

OK, so the program runs to display an image, no problem there. I copied the code for my own class so then I can display my own image(s). The problem now is that I also want to add buttons in the same program; in this case, I need to get my class to extends EasyApp. The idea is to add 4 directional buttons (up, down, left, right) in which I can move the image a number amount of pixels (with a border limit); simple. However, because my class is already extending another class (Component or EasyApp), there can not be multiple inheritance using extends. Either I have no image(s), or I have no buttons, or the code doesn't compile, or the program doesn't work. I am not so sure about implements right now (I have barely any knowledge on it).

Is there any alternative code to make this work? Or do I have to create separate classes? Or what should I do?

If I want my GUI to have a background image, I usually extend JPanel and then draw the image in the JPanel's paintComponent method and then add this JPanel to the JFrame's contentPane. Then I can add whatever components I'd like to this JPanel, but taking sure that if I add other JPanels, I call setOpaque(false) on them first.

You'll find plenty of example code for doing this here at other forum sites, and via google.

Create an ImageIcon using the Image and add the Icon to a JLabel. Then you can add the label to a JPanel using a null layout. the label can be moved by invoking the setLocation() method of the label.
