There's a FAQ entry on this:

Havoc posted this scrap of code as the approved way to do it:

  rc_style = gtk_rc_style_new ();
  rc_style->bg[GTK_STATE_NORMAL].red = 65535;
  rc_style->bg[GTK_STATE_NORMAL].green = 0;
  rc_style->bg[GTK_STATE_NORMAL].blue = 0;
  rc_style->color_flags[GTK_STATE_NORMAL] = GTK_RC_BG;
  gtk_widget_modify_style (widget, rc_style);
  gtk_rc_style_unref (rc_style);

Connect to the "event" signal. The scribble program in the tutorial does
this for a drawing_area.

You need to make a GdkGC, set a red colour, and do gdk_draw_rectangle().

You can set this in your .rc file.
