As I understand from what you've said, you already have main window with
some kind of help section which has a button called 'about'. Is that
right? So you define a function of the form

void my_callback (GtkButton *button, gpointer user_data)

and set it as a callback for that button "clicked" signal. Every time
you click that button, the function will be called, and there it's up to
you what that function would be doing. In first scenario, it should open
the glade file in usual manner, run the dialog and destroy it after the
user closes it. In the second scenario, it should just show a dialog
which was created in your main program, without destroying it, so you
can show it when button is clicked again.

You may have as many windows in one glade file as you wish. Every time
you load a file with GtkBuilder it will create brand new instances of
ALL the objects in that file (unless you specify it to create only
particular objects). So if you have both main window, and about dialog
in the same file, it means that everything was already created the first
time you called gtk_builder_add_from_file(). All you need to do is to
keep pointers to all the widgets you have, obtained with
gtk_builder_get_object(), and show/hide them on demand.
