Answer 1

For the best user experience of the file chooser, offer the file chooser in the default look-and-feel for the OS.

try {
    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception ex) {
    ex.printStackTrace();
}
JFileChooser jfc = new JFileChooser();
jfc.showOpenDialog(null);

Windows appearance

Answer 2

You have 2 choices

1. You could use java.awt.FileDialog instead. This would probably solve your issue on windows. I don't know if you need an fd to look like the windows fd on all platforms

2. You can make your own JDialog, add a JFileChooser to it (on the right), and replicate the buttons on the left.
