I too am new to Gtkmm and am working on doing this same thing.  Here is
where I am at:  I am using Glademm to generate the basic GUI outline.  I
used a 'Dialog Box' (in the Glade tools) to create my popup dialog
window.  The window is Modal, since the user needs to take care of the
popup dialog before anything else happens.  

An interesting problem I had with Glade is that it is supposed to allow
you to create the outline of a signal.  A _glade file is created that
creates virtual functions to represent your signals.  The actual class
you use for the signals is inherited from the _glade file.  The entire
philosophy behind Glade is that the programmer doesn't touch the _glade
files, but only the files inherited from the _glade files.  But with the
'Dialog' windows created in Glade (basically this allows you to
customize your input window with text entries and such), the signals do
not get created in the _glade files.  I had to break the Glade
philosophy by manually inserting the callbacks.  This fixed the problem,
but still breaks the Glade philosophy.

Anyway, now I have a dialog class that I can create in the main program
like this:

  quick_dialog *quick_dialog = new class quick_dialog();

I then run the dialog like so:

  quick_dialog->run();

At this point, I do the switch statement to decide what was clicked:

int result = quick_dialog->run();

	switch(result)
	{
		case(Gtk::RESPONSE_OK):
		{
			//do somemthing (get contents of input)
			break;
		}
		case(Gtk::RESPONSE_CANCEL):
		{	
			//do something
			break;
		}
		default:
		{
			break;
		}
	}
	delete quick_dialog;

My problem at this point is writing a function for saving what is in the
text entry box when the user clicks the OK button (this is separate than
what happens in the above switch statement  The above switch statement
will have a getInput() function that will return the contents of input
to the main program.  So, the above switch statement is inside the main
program, which creates a quick_dialog object.  The quick_dialog object
has a signal for the cancel and ok buttons when pressed.  This is
described below.  After the Ok button is clicked, and input is stored,
the above switch statement needs to get the contents of input.) I have
this so far for:

void quick_dialog::on_quick_okbutton1_clicked()
{
	input = *quick_input->get_text();
}

Where 'input' is a const gchar*.  I get an error saying that the
compiler cannot convert a ustring to a gchar, however.  I'm not sure why
I am getting this error since get_text() is supposed to return a pointer
to a gchar, not a ustring.  How do I use get_text() to store what is in
an entry into a local variable?

This post is probably a bit confusing, and I apologize for this. I may
also be taking a more difficult route to this problem.  If anyone can
post some insight, particularly to my problem of returning the result of
get_text() to a local variable, please reply.  

Thanks,
Dan
