You could use a simple JPanel instead of extendint it.
What's the point in extendint it?

Try this:
-------------------------------------------------------------------------------------
import javax.swing.*;
import java.awt.*;

public class IMIEasternButtonPanel extends JPanel {
  private JButton m_btnUp, m_btnDown;

  public IMIEasternButtonPanel(){
    setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
    setPreferredSize(new Dimension(500,50));
    addChilds();
  }

  public void addChilds(){
    m_btnUp = new JButton(new ImageIcon("up.gif"));
    m_btnUp.setMinimumSize(new Dimension(50, 50));
    m_btnUp.setMaximumSize(new Dimension(50, 50));
    m_btnUp.setPreferredSize(new Dimension(50, 50));
    add(m_btnUp);
  }

  public static void main(String[] args){
    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    IMIEasternButtonPanel iebp = new IMIEasternButtonPanel();
    frame.getContentPane().add(iebp, BorderLayout.EAST);

    frame.setSize(500, 500);
    frame.setVisible(true);
  }
}
