Position 5 buttons with GridBagConstraints in Swing

[albert kao]

How to position 5 buttons with GridBagConstraints in Swing so that the first button (B1) are at the first column, the next four buttons (B2, B3, B4, B5) are grouped together with some space between the first button and next four buttons, and the fifth button (B5) is placed at the end of the row of the screen?
i.e.
B1          B2B3B4B5
The following code does not work - there is space between each button.

JButton button = new JButton("Note");
c.fill = GridBagConstraints.LAST_LINE_START;
c.gridx = 0;
c.gridwidth = 1;
c.gridy = 5;
pane.add(button, c);

button = new JButton("Remove");
c.gridx = 5;
pane.add(button, c);

button = new JButton("Add");
c.gridx = 6;
pane.add(button, c);

button = new JButton("Add Component");
c.gridwidth = GridBagConstraints.RELATIVE;
c.gridx = 7;
pane.add(button, c);

button = new JButton("Read");
c.gridwidth = GridBagConstraints.REMAINDER;
c.gridx = 8;
pane.add(button, c);

Use a horizontal BoxLayout.

Add the first button. Add some "glue". Add the remaining 4 buttons.

See How to Use Box Layout for more information.
