In the zip file are two files: main script and an include file with the icon library. If you use your own icons, you don't need the second (don't forget to make changes in the main script, where the icons are stated!).
I hope it helps!
EDIT: Added some improvements (replacements for buttons, status-bar, custom messagebox...)
EDIT: "Fixed" listview's scrollbar (replace it with a custom one)
