3D Game

For some time I want to make a game but didn’t had the knowledge (still don’t).I used Qt to make a program for my school project and because I only know C++ I used Qt.Qt is easy to use,very good documented and I got a lot of help on MIRC that’s why I would like to make a 3D game with Qt.I googled some info but all I could find were old posts.So I came here with my questions.
1)Can you make a 3D game using Qt 3D?
2)Do I need to use some additional tools?If yes what tools?
3)What can I use to make the 3D models like the map?
4)In the game I want some objects to shatter,other to suffer some damage can I accomplish that with Qt 3D?
For now only these questions.
