Just getting it to turn is easy. Getting it right is hard for a few reasons:
First, instead of the first derivation of direction like a steering wheel in a car the stick/yoke of a plane actually controls the second derivation of the heading, meaning that pushing it a bit to the right not only causes a turn to the right but it will turn right faster and faster. So you steer by pushing/turn the yoke a bit to the right/left and wait until you reached your desired turning rate. Then you move it back into neutral position and wait until you (almost) completed the curve. Then you do push it to the opposite side until your plane is level again.
Second, there's not only the rotation along the vertical axis (Yaw) to consider: You also have Pitch (nose up/down) and Roll (rotation along longitudinal axis). What you actually did by pushing the stick to side was rolling the plane which in turn causes it to make a turn because the lifting force of the wings doesn't point straight up anymore but a bit to the inner side of the rotation. So you loose a bit of vertical lift which you have to compensate for because gravity is still the same. To generate more lift you either have to change your angle of attack or your speed. The second can be done by giving a bit more throttle but chanigng the angle of attack is trickier: Your plane hangs 'sideways' in the air so you need both the yoke and the pedals to get it right.
Third, because the plane makes a turn the outer wing is a bit faster because it has the longer path (sadly, there aren't any differentials for wings) and because it is faster it generates more lift. Yet another force to account for.
And the forth thing that comes to my mind (which applies more for gliders than for motor planes): To fly efficiently (and for other obvious reasons) you don't want to fly in another direction that your noise points at. Eg. you want the plane's longitudinal-axis be tangential to the turning curve. In a car this would be equivalent to skidding and is rather easy to avoid but air offers a lot less friction. Think of driving around in a hoovercraft...
Now a landing is trivial: as long as the debris is scattered in the direction of the runway it's considered ok.
And there's a fifth thing - you are turning the craft in a fluid medium that itself is moving. In order to get a perfect circle you have to account for wind movement throughout the turn.
I don't really know, I've never flown one for real. Judging by flying remote-controlled models and the idea that a tail is basically a direct controller of pitch and yaw regardless of form I would say it's not a big difference when turning.
Wikipedia says: "Ruddervators provide the same control effect as conventional control surfaces, but through a more complex control system that actuates the control surfaces in unison."
