why not a gui for rsync

  Yes, it is indeed is very important to know if the backup was 
  successful or if there were any errors!  I do not know the 
  resolution to this important question, but would like to present 
  how I would approach the problem, and invite comments from those 
  who know more about rsync.

  I am not sure one needs a gui.

  Here's are features of rsync that I would attempt to exploit: 
  
      a) -v option with various levels of verbosity 
      b) --stats 
      c) --log-file=foo 
      d) messages rsync prints to stdout 
      e) messages rsync prints to stderr. 

  Even on Windows, I would attempt to have a perl script fork a 
  child that issues the rsync command.  The parent perl script would 
  monitor items (b-e) and emit summary messages of the status of the 
  rsync command:  the mechanism for the message might just be prints 
  to the console or a pop-up window.  The script can have special 
  triggers for conditions such as detection of errors of certain 
  type or detection of too many errors etc. 

  So I see the need for a document that explains the format, content 
  and interpretation of (a-e) at a user level.

  My understanding is that rsync already can provide the status 
  information in an on-going manner -- how one collects, interprets 
  and displays that information is the issue.
