Hi all,
No pots for the GP-Wiz. Theoretically you could use one, but it would act in a digital fashion.
You absolutely can use standard switches for the axis inputs, (that's what they are designed for) but there are a few limitations. You first must have software which can recognize the state of the axis in question, and act on it in a digital nature. Most which can, will view a 127, or middle point, as being at rest, or an open switch state. Likewise, a 0 will equal a closure of one switch and a 255 will equal a closure on a different switch. Each axis works like this, so the limitation in this type of configuration is that two switches on opposing ends of the same axis will not register separately. One will take precedence over the other when this occurs.
If the software cannot do this internally, it may be necessary to use software which can convert the activity on the axes to a key press.
