To build a webpage that will display doc type data (dynamic data not static)

I want to create a new page that will display the doc type data(the doc type can be any custom doc type).

I have one ads approval doc type so I want a webpage that will show all the entries added in the doc type related to particular user.

Just like Orders in customer portal where the data is from Sales order doc type and it shows data related to respective customer.

Did you get the answer? If yes please tell me
