No. BorderLayout has a defined behaviour which doesn't match what you want. In
BorderLayout the outer components are all sized to their natural size (if
possible), and any extra space is only given to the CENTER component. 

You should try GridBagLayout. Set the weightx (in GridBagConstraints) of the
left and right panels to 0.25, and to 0.5 for the centre panel.
