Want to start with new AR application

Hi,
I am researching at CMU to improve civic-engagement with arts. I am wondering, is it possible to develop a web application where citizens can point mobile devices at art piece then it should provide some art information on the top of that art piece in mobile.
It does not necessarily to be in 3d format. And if it is possible then I want to know how long it would take for an average web developer to complete the task.
I appreciate your time and help.
Thanks.
