Lower wavelength photons travel more slowly than higher wavelength photons because they travel more distance oscillating up and down, rather than moving forward, per unit of time. So would it be possible to generate a photon that had such a high frequency that it moved at only feet per second? The energies used to do this would be incredible, but is it possible theoretically?

Photos are electromagnetic waves; all travel at exactly the same speed (speed of light), at least in a vacuum. There is not a significant difference between the speed of gamma rays and other photons.
In other materials, light travels slower, and yes different wavelengths travel at different speed. Not that slowly though.

One more thing. General Relativity states that the speed of light applies to all massless particles. According to Quantum Electrodynamics, and our own observations, light does have a mass (gravitational lensing). Because of this, different frequencies of light DO travel at different speeds!
