For those that have trouble starting programing screens with Tk, there is a new script that helps a lot. Editor Visual Perl/Tk.

The construction is done in the same way that would be done in a script, but visually and with some helping baloons. It is very easy to generate the code to later polish and give form.

The script is in a very young state: it is not possible to read a previously written script and redraw the design screen. But it seems a very simple and useful script.
