If num_entry is an entry, you maybe better off using
  an_int = gtk_entry_get_text(GTK_ENTRY(num_entry));

Else you'll have to g_free() the pointer returned by gtk_editable_get_chars.
other than that, what is the problem? What's going wrong?

Mind and important item: You're _not_ casting a char* to an int here. You
are converting a character string into an integer, which means it'll always
fail if there's any illegal character is in it.
