Without using Google? Reset the device from recovery. (You'll lose everything and end up with a like-new device.)

Or just use Android Device Manager to reset the password, unlock it and you're done. (Use a simple password like aaaaaa12 or something, so you can't get it wrong, then when you've unlocked the device, change it to something you'll remember.)
