No, you cannot send attachment on a mailing list, but your program is 
quite simple, you can find lots of example. You can use the project 
wizard GTK template.

First, you have to write a callback function called when your button is 
clicked something like

static void
on_sum_button_clicked (GtkButton *button, void *user_data)
{
        ...
}

This function has to get the data from both boxes, make the sum and set 
the third box. Typically, you use the second argument user_data to sent 
it all useful information, by example the address of the three boxes in 
a structure.


Then you have to connect this function to your button,

g_signal_connect (G_OBJECT (sum_button), "clicked",
                          G_CALLBACK (on_sum_button_clicked),
                          user_data);

This has to be done when you create your dialog, at that moment you can 
create the user_data with the address of all boxes.

The easiest way to create a dialog is to use a glade file, you can load 
it using gtk_builder_add_from_file and then get all widgets by their 
name using gtk_builder_get_object.
