Well, I don't know how thigs work in C++/Gtkmm.  But
I attach a working C code (both F1 and clicking on the
button runs button_callback()), so I hope you'll be able to
translate it to C++

=============================================================================
#include <gtk/gtk.h>
#include <gdk/gdkkeysyms.h>

static void
button_callback(void)
{
  g_print("Clicked!\n");
}

int main(int argc, char *argv[])
{
  GtkWidget *win, *button;
  GtkAccelGroup *accel_group;

  gtk_init(&argc, &argv);
  win = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  button = gtk_button_new_with_label("Hello!");
  gtk_container_add(GTK_CONTAINER(win), button);
  accel_group = gtk_accel_group_new();
  gtk_window_add_accel_group(GTK_WINDOW(win), accel_group);
  gtk_widget_add_accelerator(button, "clicked", accel_group, GDK_F1, 0, 0);
  g_signal_connect(G_OBJECT(win), "destroy",
                   G_CALLBACK(gtk_main_quit), NULL);
  g_signal_connect(G_OBJECT(button), "clicked",
                   G_CALLBACK(button_callback), NULL);
  gtk_widget_show_all(win);
  gtk_main();

  return 0;
}
