Java swing - how to bind my fields to a module

I am writing in java swing and I am wondering if there is a better(shorter) way to bind my object to the gui forms.

I will describe this need for an example - Zero Button :
Lets say I want on the GUI to have a number field and a button that puts zero in it. That's it.
I have a gui - form and java class . and a module class that holds all the data and does some logic.

What I will usually do (and I think its awful) is :

  1. Create the gui elements.
  2. On the module create a list that holds all the listeners to the change in the specific field.
  3. On the gui - at the beginnig add a listner to the module [send an anonymous class (value changed)]
  4. On the Module - in the setter - iterate the listeners list and notify all.
  5. On the gui - my listener changes the TextField to zero.

This whole process just to put a zero in the field next to it :-0).
and now for each field...
This is waaaay to long for me .
(Sometimes i just want to set the module to zero and than set the gui text to zero in two simple lines of code)
Is this the best practice?
Thanks.

Best practise to me is to choose a databinding framework and use it consequently. Databinding is exactly what you want - a synchronization between model (sic!) and UI

Here's a Q/A page on SO that includes a lot of links to databinding frameworks for Java Swing applications.
