Just a quick stab at what the fire() method of an actor could look
like (not tested whether Kepler likes user interaction):

  /**
   * Lets the user enter a value and broadcasts it.
   *
   * @throws IllegalActionException If there is no director.
   */
  public void fire() throws IllegalActionException {
    super.fire();

    String reply = JOptionPane.showInputDialog("Please enter value");
    if (reply == nul)
      return;

    output.broadcast(new StringToken(reply));
  }

Your actor would be derived from ptolemy.actor.lib.Source and the
output port would have to be of type STRING (defined in the actor's
constructor):
    output.setTypeEquals(BaseType.STRING);

Cheers, Peter
