As I understand, d.path with its coor= option should do
everything needed already. What is needed is to integrate d.path
into a new tool for the wx GUI which prompts the user to set
start and end points in the map display window. then it draws a
shortest path graphics layer on the screen. The legend and
scalebar "Add map elements" mini-drop down menu in the map display
GUI shows some similar rendering examples which might help. The
actual shortest path tool should probably be put in the "Analyze"
drop down menu. 
Between the "measure distance" to grab the coordinates, and "add
scalebar" as an example of drawing it the basic method can be
worked out.
