Thanks to all
I modified the script, it now works on pclos lxde (with some limitations)
Currently it can only process the following catigories:
Archiving, Editors, File Tools, Games, Graphics, Internet, Office, Sound, Video, System, and Other
You can create, show, hide and edit and assign launchers to multiple groups
You can not add catigories or sub catigories
The launchers created have basic structure, if you want to add other items like mime type, tool tips, comments, ShowIn, different language name ...etc you will have to edit the launchers manually

If any one is interested in having the script or working on it, let me know
