Gtk+ aka. GIMP Tools Kit is a framework what support GUI for Linux application (mainly). It's used under Gnome Environment in most of Linux distributions.
If you have interests in programming Gtk+ to create GUI application under Gnome or any others, why not try a simple Gtk+ app with me first?

The following code is self-explained and easy-to-understand.

/* HEADERS */
#include <gtk/gtk.h>

/* MAIN */
int
main( int argc, char *argv[] )
{
  /* declare new Gtk Widget */
  GtkWidget *window;

  /* initiate gtk app */
  gtk_init( &argc, &argv );

  /* create new Gtk Top-Level Window */
  window = gtk_window_new( GTK_WINDOW_TOPLEVEL );
  /* set window title */
  gtk_window_set_title( GTK_WINDOW( window ), "Begin GTK+ w/ [JaPh]");
  /* set window border */
  gtk_container_set_border_width( GTK_CONTAINER( window ), 10 );
  /* set window size */
  gtk_widget_set_size_request( window, 400, 300 );

  /* connect signals on destroy app */
  g_signal_connect( GTK_WINDOW( window ), "destroy", G_CALLBACK( gtk_main_quit ), NULL );

  /* show Gtk window */
  gtk_widget_show_all( window );

  /* Gtk main app activate */
  gtk_main( );

  /* app return */
  return 0;
}

Well, try to modify to see some effects.

Have fun!@
