How to fix this design?

Question

I have a main GUI with a bunch of menuItems, each has it's own listener.
4 of these menuItems do the same exact thing except for the last line whichs launches a different window for each one.
I would like to get rid of the repetive methods and have one generic class that maybe just returns the 2 files needed to launch the windows.
My problems is this:
I add the same listener to each of the 4 menuItems:
loadWindow( ActionEvent e );
in loadWindow I call the class that brings up the file selector class
       // brings up 2 file choosers first one then the other
       SelectFiles sf = new SelectFiles();
       fileOne = sf.fileOne;
       fileTwo = sf.fileTwo;
        System.out.println( fileOne );// keeps coming back null
        if( fileOne != null ){
            if( e.getSource() == menuItemOne )
                 new WindowOne();// 
          }Any ideas how do this correctly

Here's the SelectFiles class.
No "fileOne" is not static.
Thanks for taking a look at it
package SetupPackage;
import javax.swing.*;
import java.io.*;
import javax.swing.JOptionPane;
import java.awt.event.ActionEvent;
* Class for getting the 2 files needed to run the apps
* @version
public class SelectFiles extends Object {
  private JFileChooser fileChooser;
  public File xmlFile;
  public File dataFile;
  public String xmlName;
  /** Creates new SelectFiles */
  public SelectFiles(File xmlFile) {
     fileChooser = new JFileChooser();
     if( xmlFile == null ){
      // Load xml file
         fileChooser.setSelectedFile(null);
         fileChooser.setCurrentDirectory(new File("."));
         fileChooser.setDialogTitle("Select a Survey");
         int result = fileChooser.showDialog(null, "Load");
         if( result == fileChooser.APPROVE_OPTION){
             xmlFile = fileChooser.getSelectedFile();
            // reset the file chooser for the data file  
             fileChooser.setSelectedFile(null);
             fileChooser.setCurrentDirectory(new File("."));
             fileChooser.setDialogTitle("Select a Response File");
             result = fileChooser.showDialog(null, "Load");
              if( result == fileChooser.APPROVE_OPTION){
                  dataFile = fileChooser.getSelectedFile();
                  //update(this.getGraphics());
                  //new parseData(XMLFile);
                  // this was different in each method
                  // ie (window 1 window 2 window 3)
                  //loadQuestionScreen();
              else return;
         else return;      
  }// if

       int yes = JOptionPane.showConfirmDialog(null,

                 JOptionPane.YES_NO_OPTION);

       if( yes == JOptionPane.YES_OPTION ){
             this.xmlFile = xmlFile;

       else{
