VisualSubSync is a subtitle program aimed to facilitate subtitle synchronization by showing you the audio form and allowing the WORLD to see the subtitle timestamp breakdowns via a webpage and allowing them to submit corrections.

How do I see subtitles in the video preview window ?

For that you need to have VobSub installed. In the VobSub Misc properties page check Auto-reload subtitle file after detecting modification. Also, you need to name your subtitles file the same way as the video, for example : myvideo.avi and myvideo.srt or myvideo.ENG.srt. And don't forget to save your file to see the last modifications.
Note: When extracting WAV make sure you have enough disk space because there is no checking yet.
