how to add a buffered image as back ground of JFrame then add a panel on this image? [duplicate]

Answer 1

A JComponent doesn't use a Layout Manager so when you add the button it doesn't display.

Try using a FlowLayout on your component.

Also, don't use setBounds() for your frame. You should pack() and then use setLocationByPlatform(true), so the frame is displayed at its preferred size.

You would need to implement getPreferredSize() for your component so this works.
