Is there a theoretical smallest physical disturbance that would cause a wave to occur? Would it be possible to create a wave with an electrical or electomagnetic stimulus?

Any physical disturbance distorting the curvature of space-time creates gravitational waves.

Electromagnetic waves come from an electromagnetic stimulus.

if gravitation effect is via virtual particle orbits and their distortions from an unmodified state, is there a possibility to affect the particles in some way with an electric charge or magnetic fields? Does not the casimir effect show that the pairs can be sensed in a rather crude physical way, therefore, manipulable?

Gravitational waves come from certain accelerations of mass. The mass doesn't care how it was accelerated; if it's charged, the it can be from an EM interaction. But it's unlikely that this acceleration would be very large if you had enough mass to make anything significant.

 

The Casimir effect is not gravitational in nature. You're mixing two distinct effects.

yes, I was mixing the two as they seem related through some fundamental character. If the distortions, or "stretching" of the virtual particle pair orbits relate to gravitation, the "stretching" of time (slowing) becomes a phenomena of gravitation as it takes longer to circumvent an elliptical orbit vs. a circular one for the affected pair. The pair must appear/annialate within a certain time period, and the longer physical route demands time to slow down so that the exchange can be accomplished within the time limit required.
