Convert 'Cute File Browser' to plugin

Hello everyone,
I’m trying to make a plugin based on “Cute File Browser” ( but I’m having a lot of trouble with it, as I’m pretty newbie to PHP.
I’ve tried to do it but I’m really confused about how I must do it. :C
Can somebody help me?

Thank you very much! :wink:

Short of doing it for you, what help do you need exactly?
