Can I use QIODevice for connecting my program to my webcam?

QIODevice is a pure abstract class, so you can't use it directly. But you can use QFile. If you're running U*ix and your webcam supports reading from /dev/something then it's possible that you can use it this way.

And how can I connect my program to my webcam and display image in my program?

That's a completely different question and I think it is beyond the scope of this forum (and in general it depends on both the hardware and software available).
