Yes, just as by winging your arm while swimming you can make it emit water waves.

However, the accelerating mass required to produce gravitational waves has to move in a non-spherically symmetric way and the power emitted by just swinging your arm is vanishingly small.

We will know more when gravitational waves are actually detected!
