Your requirement seems to be a relatively simple use of BorderLayout.

The code snippet below assumes the panel are being added to a JFrame. Hence the getContentPane() calls.

javax.swing.JPanel jPanel1 = new javax.swing.JPanel();
javax.swing.JPanel jPanel2 = new javax.swing.JPanel();

jPanel1.setMaximumSize(new java.awt.Dimension(60, 32767));
jPanel1.setMinimumSize(new java.awt.Dimension(60, 100));
jPanel1.setPreferredSize(new java.awt.Dimension(60, 300));

getContentPane().add(jPanel1, java.awt.BorderLayout.WEST);

getContentPane().add(jPanel2, java.awt.BorderLayout.EAST);

Specify the maximum, minimum and preferred width of jPanel1 to be 60 px. Leave JPanel2 to "float".

If separation of the panes is required add a third pane of fixed width (say 5 px)

getContentPane().add(jPanel3, java.awt.BorderLayout.CENTER);
