create a Question class with the following fields
String question;
String[] choices;
int correctAnswer;
the frame will have 2 components
questionsPanel at 'Center'
buttonsPanel at 'South'
questionsPanel will be a CardLayout, each 'card' will be a JPanel with a JLabel
for the question and JRadioButtons for the choices
buttonsPanel will have JButtons 'previous', 'next' (and possibly 'finish')
the buttons just have cardlayout.next/previous
should be enough to start you off
