what would I do instead? Just have one generic widget that would be used for
all of them?
example:

typedef struct {
    GtkWidget *window;
    GtkWidget *widget;
} Window;

then use it like:

win->widget = gtk_label_new();
...
win->widget = gtk_button_new_with_label();
etc...

would this save memory that is malloc'd for this program?

Ok, here is my dilemma now:

is there a difference between the following g_malloc() calls

Window *win = g_malloc(sizeof(Window *));
Window *win = g_malloc(sizeof(Window));

if there is, should I use one over the other?
