Callbacks in gtk always take the object emitting the signal as first 
argument, so if you connect to a function that takes only one parameter 
(gtk_destroy_widget) it operates on the button which emits the signal. 
In general you have to check in the docs the prototype of the callback 
for the signal you are using since it may takes different args and may 
have to return a value and connect a proper callback function. In this 
particular case though you can use the following trick: 
g_signal_connect_swapped (G_OBJECT(cancel_button), "clicked", 
gtk_widget_destroy, another_window); so that another_window is passed as 
first arg to gtk_destroy_widget instead of cancel_button.

PS: a window with a cancel button that closes it... are you sure that 
GtkDialog and its "response" signal are not what you are looking for?
