No. Windu was dead immediatly after he was thrown out of the window. And after that, he would already be in his sixties during Episode IV. That makes him nearly 94 in The Force Awakens.

The (for now) logical choice remains Plagueis. He was known to create life, and as a master of Sidious, he knew about his plans, and that he was useless in the eyes of Palpatine.
