How much newtons is needed to turn a wheel with radius 1 meter and mass of one kilogram and width of 1cm, exerting force on the outer circumference of the wheel and assuming no friction occurs?

You can use any amount of force you want. The only thing that will change is the angular acceleration. The smaller the tangential force, the smaller the torque, and hence the more time it will take to accelerate up to any given rotational speed.

In other words, to get a unique answer to your question, you must specify

- what angular velocity you want to reach
- how much time you want it to take to reach that angular velocity
