I did not want to use an external module. I've been trying to do it with 
a Tkinter canvas.

It shouldn't be that difficult to do. When the user clicks the mouse on 
one letter, that letter become an anchor and as the mouse moves I need 
to determine which letters intersect the imaginary line connecting the 
current mouse position to the anchor and draw the bounding box around 
those letters.

The problem is I don't know how to do it using Tkinter canvas events.
