All of the tutorials start off the same. We open a window to make sure that the GTK libary is installed and working.

#include <gtk/gtk.h>

int main(int argc, char *argv[]) {

	GtkWidget *window;

	gtk_init(&argc, &argv);

	window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
	gtk_window_set_title(GTK_WINDOW(window), "Astroids Tutorial");
	gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
	gtk_window_set_default_size(GTK_WINDOW(window), 640, 480);
	gtk_window_set_type_hint(GTK_WINDOW(window), GDK_WINDOW_TYPE_HINT_UTILITY);
	g_signal_connect(window, "destroy", G_CALLBACK(gtk_main_quit), NULL);

	gtk_widget_show_all(window);

	gtk_main();

	return 0;

}

Compile with:

$ gcc `pkg-config --cflags gtk+-3.0` main.c `pkg-config --libs gtk+-3.0`

Run with:

$ ./a.out
