You use lookup_widget only to inquire about the pointer to the CList.
Once you've got that one, you modify a row by calling gtk_clist_set_row_data
After you called that one, the CList should be updated.

You need to explicitly set a window to be modal, by calling a GTK function
the name of which I forgot. However, as you're using Glade, you'd want to
tell Glade to call it for you. Look up the Properties dialog in Glade for
the topmost widget of your dialog, there is a button labeled "Modal"

It really depends on what you wanna do with the window. I try to avoid
keeping globals pointing to secondary windows, but sometimes it is handy. 
For the main window, I think it is a good idea to do so in any case.
