I think you could implement in you application, it's more about data than graphics. The common is the milestone at the end of some task/phase, so you could usually define in the task/phase form if it has a milestone and use the date of the end of task. So if you change the date of the end of task, you automatically change the milestone.
You really need change the class only if you thing about show it graphically.
If is the case, you can copy the function "dependency" and adjust to link between a task and a milestone, but I yet believe you only will need adapt the end to start case.
