First of all, building a 'notification system'
is incredibly easy, it's just javascript popups.
No it's not "just javascript popups". Notification systems are clean, and non-intrusive ways of notifying the user of an important event or alert. There is no such thing as "just javascript popups". It takes an understanding of both UX and UI to create.
Secondly - don't do popup notifications ever.
They are the antithesis of user intent. Nobody
ever 'wants' to see a popup.
I rarely "go with the grain", but I think Apple, Ubuntu, and a huge amount of web applications would say you're wrong. Users like to be notified of things, but they don't like to be interrupted. Notifications like this are the best way to achieve this.

I don't think you understand what a notification is. A notification is purely for informational purposes. Popups in general can sometimes be better than the alternative.
