How to write a loop command for pdf2djvu

How do I write a loop command to periodically check a given folder and then create a djvu file from any pdf it finds.
pdf2djvu works great but I'm looking to set up a "hot folder" for general office staff to use.

Well in my opinion this is what cron is for, you can just have the script to look in to that folder for new files or modified within X amount of time and convert it, then setup the crontab of the user that will execute it every X amount of minutes, days or whatever you need.

Which languages can you use? Can you call inotify?

This is what I have so far.
It works great except if it kick's in while someone is uploading a pdf file.
The pdf gets deleted before it's processed.

find /home/qwikchk/ -iname '*.pdf' -print0 | xargs -0 -IX pdf2djvu -o X.djvu X
mv /home/qwikchk/*.djvu /var/www/html/qwikchk/files/
rm -f /home/qwikchk/*.pdf
chown -R apache:apache /var/www/html/qwikchk/
