java dynamically adding JPanel urgent now2

every jpanel has the same look: Terminal X (x stands for any number) payin - button payout - button credit - label the gui is already done with JComboBox to select any terminal but for better visaulisation it should be done with jpanles. i have already made the first jpanel but dont know how to do this dynamically. also if there are more than the content pane can take there should be scrolling. functions: choose terminal with jcombobox (already done) now do it with click on the jpanel too. show current credit for all terminals action listener for all buttons ([login to view URL]("payin from terminal "+terminal) is fine for this project.
