Adding Menu to Photoshop

[NoneForce]

Hi,
a friend of mine is working in a photogallery and they are using a software for archiving ,re-printing,accounting, but it's not a standalone software,it's a part of the photoshop.
i want to know how we can do this? by using photoshop's sdk?
here's the site :

I think that there are two ways to achieve this goal:

first to write a plug-in for photoshop that creates the menus while loading...
and the second one maybe creating a smart patch to change the exe.
