You can make a struct with the pointers to two widgets inside, 

struct {
  GetWidget *name, *pass;
} myTwoWidgets;

or an array of two pointers

GtkWidget *myTwoWidgets[2]

and pass a pointer to the struct/array as data. In both cases you will
have to typecast the gpointer in the handler to the corresponding type.

If you're using Glade, you can also pass the reference to the parent
window, and do lookup_widget (parent, "xxxx") for each widget inside the
handler.
