I'm not familiar with this subject but I believe the pango package is involved.

I found a "hello world" application that uses Gtk, but can't remember where I found it... anyway I used google translation service to get Hindi words for "Hello World!" and pasted those in to the source. You can simply copy the code and command to compile it into a program named a.out is on the first comment line.

If I find the source of the tutorial I'll come back and update meanwhile here it is:

// gcc -Wall -g hellohindi.c `pkg-config --cflags gtk+-2.0` `pkg-config --libs gtk+-2.0`
#include <gtk/gtk.h>

/* This is a callback function. The data arguments are ignored
* in this example. More on callbacks below. */
static void hello( GtkWidget *widget,
gpointer data )
g_print ("नमस्ते विश्व!\n");

static gboolean delete_event( GtkWidget *widget,
GdkEvent *event,
gpointer data )
/* If you return FALSE in the "delete-event" signal handler,
* GTK will emit the "destroy" signal. Returning TRUE means
* you don't want the window to be destroyed.
* This is useful for popping up 'are you sure you want to quit?'
* type dialogs. */

g_print ("delete event occurred\n");

/* Change TRUE to FALSE and the main window will be destroyed with
* a "delete-event". */

return FALSE;

/* Another callback */
static void destroy( GtkWidget *widget,
gpointer data )
gtk_main_quit ();

int main( int argc,
char *argv[] )
/* GtkWidget is the storage type for widgets */
GtkWidget *window;
GtkWidget *button;

/* This is called in all GTK applications. Arguments are parsed
* from the command line and are returned to the application. */
gtk_init (&argc, &argv);

/* create a new window */
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);

/* When the window is given the "delete-event" signal (this is given
* by the window manager, usually by the "close" option, or on the
* titlebar), we ask it to call the delete_event () function
* as defined above. The data passed to the callback
* function is NULL and is ignored in the callback function. */
g_signal_connect (window, "delete-event",
G_CALLBACK (delete_event), NULL);

/* Here we connect the "destroy" event to a signal handler.
* This event occurs when we call gtk_widget_destroy() on the window,
* or if we return FALSE in the "delete-event" callback. */
g_signal_connect (window, "destroy",
G_CALLBACK (destroy), NULL);

/* Sets the border width of the window. */
gtk_container_set_border_width (GTK_CONTAINER (window), 10);

/* Creates a new button with the label "Hello World". */
button = gtk_button_new_with_label ("नमस्ते विश्व!");

/* When the button receives the "clicked" signal, it will call the
* function hello() passing it NULL as its argument. The hello()
* function is defined above. */
g_signal_connect (button, "clicked",
G_CALLBACK (hello), NULL);

/* This will cause the window to be destroyed by calling
* gtk_widget_destroy(window) when "clicked". Again, the destroy
* signal could come from here, or the window manager. */
g_signal_connect_swapped (button, "clicked",
G_CALLBACK (gtk_widget_destroy),

/* This packs the button into the window (a gtk container). */
gtk_container_add (GTK_CONTAINER (window), button);

/* The final step is to display this newly created widget. */
gtk_widget_show (button);

/* and the window */
gtk_widget_show (window);

/* All GTK applications must have a gtk_main(). Control ends here
* and waits for an event to occur (like a key press or
* mouse event). */
gtk_main ();

return 0;

I hope that helps :)
