No. D + T or D + D fusion reaction produces neutrons and hard gamma radiation. The special glass cannot capture the energy of these directly. The natural fusion reactor has a blanket that is literally thousands of kilometers thick. It effectively converts much of this into longer-wavelength electromagnetic radiation, from ultraviolet to infrared, with quite some visible light. That's what the special glass can make use of. Also, the highly radioactive blanket is kept hundreds of millions km away from consumers, which helps alleviate the problem of disposing of radioactive waste. With a planet-based fusion reactor, we'd have to think where to put thousands and thousands of tons of slightly radioactive concrete which would realistically serve as a blanket.
