You say you have tabs. I assume you are using a JTabbedPane. I would
make the content in each of the tabs its own class that implements an
interface.

public interface TreeWidget {
  public void loadTree(Object parameter);
}

public class TabPanelA implements TreeWidget {
  JTree tvwTreeA = new JTree(new DefaultTreeModel(new
DefaultMutableTreeNode("Root")));
  ... // other stuff here
  public void loadTree(Object parameter) {
    ... // stuff here to load tree
  }
}

public class MyFrame extends JFrame {
  JButton cmdLoad = new JButton("Load");
  JTabbedPane tabbedPane = new JTabbedPane();

  public MyFrame() {
    this.setSize(800, 600);
    this.setVisible(true);
    this.getContentPane().setLayout(new BorderLayout());
    this.getContentPane().add(cmdLoad, BorderLayout.NORTH);
    this.getContentPane().add(tabbedPane, BorderLayout.CENTER);
    tabbedPane.addTab("Panel A", new TabPanelA());
    cmdLoad.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        Object parameter = ...// parameter to pass to the tree
 
((TreeWidget)tabbedPane.getSelectedComponent()).loadTree(parameter);
      }
    });
}
