Mike,

you would have to provide a small (inner) helper class and put 
an instance of this into your DefaultMutableTreeNodes.
Here's some untestet code:

class DBData {
  public String kapitelName;
  public int kapitelID;
  public DBData(String name, int id) {
    kaptelName = name;
    kapitelID = id;
  }
  //this will be displayed
  public String toString() {
    return kapitelName + " " + kapitelID;
  }
}

put it in like this:
DBData data = new DBData(queryDataSet2.getString(2) queryDataSet2.getInt(3));
.. new DefaultMutableTreeNode(data);

retrieve ID like this:
DefaultMutableTreeNode node = ...
DBData data = (DBData)node.getUserObjject();
int id = data.kapitelID;
