Adding a custom icon (for a hand written script) to notification area xfce

Question

I don't use unity, and I wrote a simple script to start programs used in recording audio. (Jack, guitarix, etc) I would like to know is there a command that will allow me to create an icon in the notification area of XFCE 4's panel? Also can I use this icon to kill all PID's created by the script?

#!/bin/bash
qjackctl -s &
jackPID=$!
env sleep 2s
guitarix &
guitarixPID=$!

#kill $jackPID & kill $guitarixPID
exit

i already have the PID's stored to local variables, but these can easily be written to a file if necessary

You should take a look at Yad, an advanced Zenity fork. It supports systray notification icons and can be installed from this PPA.
