Without XML markups it would be something like

#include <gtk/gtk.h>

int main (int argc, char **argv)
{
  gtk_init (&argc, &argv);

  GtkWidget *fen = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  g_signal_connect (G_OBJECT (fen), "destroy", G_CALLBACK (gtk_main_quit), 
NULL);

  GtkWidget *label = gtk_label_new ("This is a Multi-line label.\nSecond 
line\nThird line");
  gtk_container_add (GTK_CONTAINER (fen), label);

  PangoFontDescription *font_desc = pango_font_description_from_string ("mono 
8");
  gtk_widget_modify_font (label, font_desc);
  pango_font_description_free (font_desc);

  GdkColor color;
  gdk_color_parse ("#FFBF00", &color);
  gtk_widget_modify_fg (label, GTK_STATE_NORMAL, &color);

  gtk_widget_show_all (fen);
  gtk_main();

  return 0;
}

You may want to take a look at the documentation for further details about 
functions.
