A toggle button is a subclass of button which is a container with one
child, which can be found with GTK_BUTTON(widget)->child;
So, if you know that this is a label, you can change it with:

   gtk_label_set(GTK_LABEL(GTK_BUTTON(togglebutton)->child), "new label");

I had trouble with this when I started learning GTK - I almost reported
it as a bug!

gtk_label_set_justify() is only relevant if a label has more than one line.
It sets the justification of the lines as a group, i.e. all the left edges/
middles/right edges lined up.

What you really wanted was the gtk_misc_set_alignment() function - a label
is a GtkMisc, which has an alignment and padding.

Left align:
  gtk_misc_set_alignment(GTK_MISC(label), 0.0, 0.5);
Center align:
  gtk_misc_set_alignment(GTK_MISC(label), 0.5, 0.5);
Right align:
  gtk_misc_set_alignment(GTK_MISC(label), 1.0, 0.5);
