read the TreeView docs, and Gtk2::Menu for Gtk2::Menu::popup.  you'll 
also want the Gtk2::Gdk::Event::Button.

basic procedure:

1. connect to the "button-press-event" on the treeview.  if you want 
right-clicking to select the row before popping up the menu, use 
signal_connect_after() to connect to the button-press-event, so that 
the default handlers run first.
2. in the handler:
   a)  if $event->button==3 (the right mouse button), create your menu 
and call $menu->popup.  the menu pos func can be undef unless you want 
to do something fancy.  pass $event->button to popup() so that the menu 
tracks the correct mouse button.
   b)  if you need to know which row the user clicked on:  ($x, $y) = 
$event->coords  tells you where the user clicked,  and you can pass 
those to $treeview->get_path_at_pos  to find the path, column, and cell 
coords of the click.
   c)  remember that returning TRUE or FALSE from the handler controls 
whether the default handlers run.
