Assign the location for the clicks in an Autohotkey script when script starts

Hi, I have an Autohotkey script I use to do several actions in BMC Remedy. Problem is that if someone else wants to use this script or I change the position of the Remedy window, the clicks won't be in the right position. Is there any way to create some GUI or something similar that when the script starts will ask you first to assign the position of all the clicks ? This is the code I have :
