What you are going to want to build is a full bridge (H bridge) inverter with either mosfets of igbt's connected to a step up transformer. What frequency are you intending to run it at? 60hz? Your best bet for a PWM chip is either a tl494 or a sg3525. If you want extreme simplicity you can go with the well known 555 timer. The 555 however is not 100% meant for inverter oscillators and it lacks regulation capabilities and some more frills and thrills that other chips such as the tl494 support.
