Compile error of GTK

[Vegard|drageV]

I'm trying for the first time to make my own gui-program, with menus and all to launch a series of commands and scripts I've written. Google led me to http://www.gtk.org/tutorial/ , where I am to compile the program base.c, given as an example in the text under the link "3. Getting started".

Compiling gives this error:
-------------------------------------------------------------------------------------------------------
[EMAIL PROTECTED]:~/gtk$ gcc base.c -o base `pkg-config --cflags --libs gtk+-2.0`
Package gtk+-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-2.0' found
base.c:1:21: gtk/gtk.h: Ingen slik fil eller filkatalog
base.c: I funktionen 'main':
base.c:6: error: `GtkWidget' undeclared (first use in this function)
base.c:6: error: (Each undeclared identifier is reported only once
base.c:6: error: for each function it appears in.)
base.c:6: error: `window' undeclared (first use in this function)
base.c:10: error: `GTK_WINDOW_TOPLEVEL' undeclared (first use in this function)

I can not find the files gtk+-2.0.pc ,  gtk/gtk.h anywhere. I tried installing the developmentfiles with:

            apt-get install libgtk2.0-dev

but this package has dependencies to other packages wich is not available to me, namly:

            libpango1.0-dev, libx11-dev, xlibs-dev

Is there anybody who have any idea on what I can do to fix the compiler?

I have Debian Sarge, kernel 2.4.27-2-686
