show one panel after button is clicked and other panel when second button is clicked in the same frame

Question

I am creating a Swing based application , which actually consist of two buttons as shown below -

now what i want is when first button is clicked it must perform a action like showing a panel containing label, textfields , and some buttons in the same frame as shown below -

and when second button is clicked it will show another panel in the same frame as shown below ..

the thing is i am not understanding how to make this interface in action by providing event handler and action listener .. So please letme me know how can i archive this . Any help would be appreciated .. Thanks

There are 2 approaches.

1. CardLayout based.
   Create all the panels (empty, panel with fields, panel with list) and add them in a container with CardLayout (the empty one is default). On click buttons swap visible cards (panels) showing necessary one.

2. Recreation based.
   On click button create a new panel with new content. Remove the old one from container and add the newly created pane. After then call:

    container.revalidate(); container.repaint();
