Sample code - the script handles one file at a time.
Enhance it for your need.

Code:
#!/bin/bash
#Script Name : encrypt.sh
#run the script in the background and forget about it i.e. ./encrypt.sh &
old_file_count=0
while true; do
  curr_file_count=`ls | wc -l`
  if [ $curr_file_count -gt $old_file_count ]; then
    old_file_count=$curr_file_count
    new_file=`ls -rt | tail -1`
    echo "New file found : $new_file : do whatever you want now"
    #gpg -r $new_file.gpg --encrypt-files $new_file
    #mv $new_file.gpg /where/ever/you/want
  fi
  #Change the sleep timer to your need
  sleep 5
done

You can also add this as a cronjob with necessary changes.
