You have at least two solutions:

- group all your widgets in a structure and pass this strucyure as
user_data to g_signal_connect;

- add references to the other widgets to the button using
g_object_set_data, something as:
g_object_set_data (my_button, "spin1", my_spin_button1);
and then, in the signal handler,  get back the spin button with:
my_spin_button1 = GTK_SPIN_BUTTON (g_object_get_data (button, "spin1"));
