Adding a label on a panel

Question

i have around 7 buttons. Whenever i click on any 1 button, a label with an ImageIcon parameter needs to be displayed on a panel.
when the user clicks the second button, another label with an ImageIcon gets added on the same panel(now the panel has first label+ second label).
These labels can also be moved on the panel using mouse(i have the code to make the label move on the panel).
How do i add these labels on my panel on their respective button clicks?? thanx in advance
