What ahundiak is saying is that your subject "Question for pro" doesn't really tell us what your post is about. It would be more helpful for everyone if the subject said something like "flow chart for website" or something like that.
And I don't get what you're asking. Are you looking for a program to create a flow chart of a program's control flow/objects/functions/etc? If so, then look into MS Visio (no, I don't usually recommend MS products, but this is the only one I know of to create flow charts). You could also search the web for UML.
