uploading contents on a FP2003 website

I have to mantain a website in Frontpage2003.
My customer need to setup few directories into the site into where some
users should upload some contents.
The users enabled to upload should have a password and a proper permission.
The uploaded contents (mainly PDF documents) should be visible to all the
website visitors.
A kind of simple CMS in FP2003
Is there a way to do this in a simple manner without ASP programming?
I am not a great expert of FP2003.
I have been trying to solve the problem using a PHP script (easyupload) but
it needs to set up the uploading directories to be accessible to all the
users,...not my case!
Any help???
Thanx in advance
