Personally I'd have all buttons visible but just enable and disable
appropriate ones according to the state of the application. Disabled
buttons look disabled and users expect that sort of thing.

I'd expect users to be confused by having buttons magically appear and
disappear. YMMV.

If none of the above bears any relation to what you are trying to
achieve, frankly its because you have failed to adequately explain or
provide a runnable example.
