Tool for creating a Java program designer

The script is a handy tool for creating constructors for Java programs.
How it all works:
You are loading a Jar file for the base of your constructor. The file is divided into components, pictures and sounds from this file are automatically selected.
Next, you are invited to add your own pictures and sounds as alternatives. Of these, when assembling, the user will choose.

In addition, you can import the constructor you have created into a file with the * .kost extension and exchange such files between the owners of the script.

An example of the script: http://sleza-mobile.ru/example/index.php
Admin panel for the script: http://sleza-mobile.ru/example/adm.php
(For authorization, go here http://sleza-mobile.ru/example/enter.php Username and password: admin)
