Create a tag that is used to tag each of the clickable names. Then 
connect a handler to the "event" signal of the tag. See the following 
for more info:
on the event handler signature.

For example:

def hyperlink_handler(tag, textview, event, iter):
if event.type == gtk.gdk.BUTTON_RELEASE:
#figure out which hyperlink name was clicked and query

buffer = textview.get_buffer()
tag = buffer.create_tag("hyperlink", foreground='blue')
tag.connect('event', hyperlink_handler)
iter = b.get_iter_at_mark(b.get_insert())
b.insert_with_tags(iter, name, tag)

The testtext.py example in the PyGTK tutorial has an example of handling 
tag events:
