have you used pickle?  if the data is as simple as you say it is, you
will be able to read the pickle file.  2nd, it will be a lot less code
really.  You just load and unpickle the file into a variable.  After
any edit in the gui, repickle it to the same file.  You would have to
do the same if you edited the text file, except you would need a couple
of lines code to parse the string, etc.

check here for a simple example :
