There are planes like the Piper PA-22 which have interconnected (via springs) rudder and ailerons. Either rudder pedals or wheel may be used to give an acceptable coordinated turn - although more precision (i.e. keeping the slip ball centered) is had by using both together.
And of course slips and skids are still possible, although you are fighting the springs.
My experience with most high-wing light aircraft is that mild turns can be made using rudder only, if you aren't in a hurry.
