Thank you for taking the time mate ;)
This is he code changed with your code.
when the title,first &last name is null it still only runs the 1st JOptionPanel and dosn't pass to the 2nd ??
here is the code
  void NewShoeOrderjButton_actionPerformed(ActionEvent e) {
    String check=null;
    if(TitleComboBox.getSelectedItem() != null &&
       FirstNameJText.getText() != null &&
       LastNameJText.getText() != null)
      check=TitleComboBox.getSelectedItem()+FirstNameJText.getText()+LastNameJText.getText(); //the rest of the thing.......;
//then you check "check":
    if(check != null){
      //show the first optionpane
      String[] options = {"Yes", "Cancel"};
      String d= System.getProperty("line.separator");
      int result = JOptionPane.showOptionDialog(null,
          "Do you really want to add a new shoe order for:"+ d +
          (String) TitleComboBox.getSelectedItem()+" "+FirstNameJText.getText()+
          " "+LastNameJText.getText(),"New Order",
          JOptionPane.YES_OPTION,
          JOptionPane.INFORMATION_MESSAGE,
          null,
          options,
          options[0]);
      switch(result){
        case JOptionPane.YES_OPTION: // Add your code for no
          setFieldsEditable(false);
          break;
        case JOptionPane.NO_OPTION: // Add your code for yes
          // just playing with button
          setFieldsEditable(true);
          break;
    }else{
      //show the second optionpane
      JOptionPane.showMessageDialog( null,
                                     "There is no order", "No Order",
                                     JOptionPane.WARNING_MESSAGE);
  }
