but Javadot often is as obtuse as Java

;; Java
final JFrame w = new JFrame("Test");
JButton eb = new JButton("Exit");
eb.setBackground(Color.red);
eb.addActionListener(new ActionListener(){
      public void actionPerformed(ActionEvent e) {
        System.exit(0);}});
w.getContentPane().add(eb); 
w.pack(); w.show();

;; JScheme
(import "javax.swing.*")
(define w (JFrame. "Test"))
(define eb (JButton. "Exit"))
(.setBackground eb Color.red$)
(.addActionListener eb 
   (Listener. (lambda(e) (System.exit 0))))
(.add (.getContentPane w) eb) 
(.pack w) (.show w)
