GTK Widget question

    I have a GTK+ GUI which has a keyboard in it, with all 26 letters, and a screen/label on top. When i press a key on the key board, i want it to add to string for the display. How do i do this? I know i need to use String Concatenation, but its the actual callback function i'm having problems with.

    If i have a string, declared in the main
    char[] display = ""
    And a button
    g_signal_connect (G_OBJECT (button), "clicked", G_CALLBACK (callback), (gpointer) "a");
    How do i add the letter "a" onto the end of the display string?
