A gravity wave occurs at the lowest of the lowest of low frequencies. In order to produce such a wave the object resonating would have to be many many miles long and be stronger than any material known to man as well as incredibly heavy. Think of a very long cable woven from a neutron star. That’s about what it would take :)
The concept has of course been written about a fair bit on science fiction. The dark forest trilogy comes to mind and used a gravity wave generator built into the hull of a massive ship whose purpose was to alert alien life to the existence of the earth.
