Here's one possible solution.

Presumably, the parent window created the modal window, so has a reference
to it. Before opening the modal window, the parent can do:

  // Save the label object where the string will be placed
  modalWindow.setUserData("parentField", myLabel);

The modal window can then, when it gets its "close" event, modify the
parent:

// "this" is the modal window
this.addListener("close",
  function(e)
  {
    // Get the parent field to which we want to set the modal
window-obtained string
    var parentField = this.getUserData("parentField");

    // Get the value from the text field in the modal window
    var string = textField.getValue();

    // Set the parent field with the string value
    parentField.setValue(string);
  });

There are many other implementations to do the same thing, but this should
give you some ideas.
