It's not something I need in my own work, but I think it would be a
good addition to matplotlib and I'd be happy to include it.  To that
end, I wrote some demo code to get you started!  I implemented an
object picker (currently only for tick labels and lines but this can
easily be extended to include the other elements of the figure).

I also wrote the start of a line properties dialog.  It should be
straight forward to extend to incorporate the other line properties,
(markeredgecolor, etc...) and then to do the same for a text
properties dialog, etc....

I needed to add a few things to matplotlib to make this easier, so
you'll need to grab the snapshot at 

  http://nitace.bsd.uchicago.edu:8080/files/share/matplotlib-0.42a.tar.gz

and see the file examples/object_picker.py.  

Good luck!
