I’ve tried porting Karga to PureSwing (with default Desktop). Most went quite smootly 
below are some issues i’ve faced (some important some not)
- ImageIcon(url) waits indefinetely if given url is an animated gif
- JDesktopPane does not correctly stack (render and dispatch mouse events) components
- JLabel doesn’t support multilines (separated with \n)
- JFrame.pack() does not take window decorations (title bar, borders) into account
- JFrame.setDefaultCloseOperation(CloseOperation.EXIT_ON_CLOSE) does not work
- switching to another window and coming back results in losing keyboard focus. we even can not regain it by clicking
- pressing Tab does not iterate over focusable components
and some opinions:
- re-adding JOptionPane.showInternalXXDialog makes sense to show the dialogs embedded in same window
- re-adding basic HTML support can make sense (JEditorPane, JTextPane, html in JLabel) they are very handy to create multi color/line/format texts.
and below is a test case:

JPanel backgroundPanel = new JPanel();
backgroundPanel.setBackground(Color.LIGHT_GRAY);
desktop.add(backgroundPanel, BACKGROUND_LAYER);
// this should be centered in frame but is not
backgroundPanel.setBounds(new Rectangle(50, 50, 700, 500));
backgroundPanel.addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent event) {
System.out.println("mouse clicked on background");
}
});
// this text field should be rendered on top of background but is not
JTextField textField = new JTextField();
desktop.add(textField, HELPERS_LAYER);
textField.setBounds(0, 50, 200, 20);
textField.addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent event) {
System.out.println("mouse clicked on textField");
}
});
JFrame frame = new JFrame("PureSwing - test");
frame.setDefaultCloseOperation(CloseOperation.EXIT_ON_CLOSE);
frame.add(desktop);
frame.pack();
frame.setVisible(true);
EventQueue.runLoop();
}
}
