I need help on something

Extend a JPanel for drawing. Set its LayoutManager to null. Create your buttons and
issue a setBounds(x,y,width,height) for each of them before your to place them on the excact spot on your panel by a simple thePanel.add(button);
Important:
Do all your draiwing by overriding the JPanels paintComponent(Graphics g) method. Don't 'paint' the buttons, they will be placed on top og the drawing after the paintComponent method exits.

Good Luck !

PS: you can animate (move) the buttons by calling the buttons' setBounds and then the panel's validate/repaint method.
