GUI for adding/removing users & home dirs for PureFTP?

We have DroboShare. I know we can play around with command lines, except that I want to delegate adding and removing FTP users and their home directories to much less techie co-workers.
Is there anything existing that can do it?
Webmin is written, I think, in Perl… but I have no idea if it could be installed on Drobo some way. I am new to this device, so I would love some help.
