> pane.add(showButton, BorderLayout.SOUTH);

Instead of adding your submit button to pane, create a new panel (with FlowLayout) and add your submit and new cancel button to it. Then add that new panel to pane.

JPanel buttons = new JPanel(new FlowLayout());
buttons.add(showButton);
buttons.add(cancelButton);
pane.add(buttons, BorderLayout.SOUTH);

I wan to add it in the "yes or no" command there. It's a pop up window that prompt users whether they are sure with their answers anot.

the window will show "ARe you confirm with this decision?" and there's a yes/no button to click on. but i dunno how to add in the cancel button in there.

you're missing the voteButton type, should be:

private JPanel createPane(String description,
                              JRadioButton[] radioButtons,
                              JButton cancelButton, JButton voteButton) {
