I think your problem is "gdk_bitmap_create_from...";  The depth of your pixmap
does not match the depth of your drawable.

Try this code, with "gdk_pixmap_create_from..."

#include <gtk/gtk.h>

#define icon_width 90
#define icon_height 16
static char icon_bits[] = {
 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xf0,0x7f,0x00,0x00,0x00,
 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xf0,0xff,0xff,0x03,0x00,0x00,0x00,0x00,
 0x00,0x00,0x00,0x00,0xf0,0xff,0xff,0xff,0x1f,0x00,0x00,0x00,0x00,0x00,0x00,
 0x00,0xf0,0xff,0xff,0xff,0xff,0xff,0x01,0x00,0x00,0x00,0x00,0x00,0xf0,0xff,
 0xff,0xff,0xff,0xff,0xff,0x0f,0x00,0x00,0x00,0x00,0xf0,0xff,0xff,0xff,0xff,

 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00};

main(int argc, char ** argv)
{
  GtkWidget *window, *pixwid;
  GdkPixmap *pixmap;
  GdkColor bg, fg;
  GdkVisual *vis;

  gtk_init(&argc, &argv);

  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  vis = gtk_widget_get_visual(window);

  /* This colour management IS WRONG. You must change it */
  bg.pixel = 0x000000;
  fg.pixel = 0xffffff;

  pixmap = gdk_pixmap_create_from_data(window->window, icon_bits,
                                       icon_width, icon_height, vis->depth, &fg,
&bg);
  pixwid = gtk_pixmap_new(pixmap, NULL);
  gtk_container_set_border_width(GTK_CONTAINER(window), 100);
  gtk_container_add(GTK_CONTAINER(window), pixwid);
  gtk_widget_show(pixwid);
  gtk_widget_show(window);

  gtk_main();
