You can also use the FreeType backend supposedly without GTK.  PAPS, a
postscript printing program, does exactly that:

bash-2.05$ ldd paps
        libpangoft2-1.0.so.0 => /usr/lib/libpangoft2-1.0.so.0 (0x40024000)
        libpango-1.0.so.0 => /usr/lib/libpango-1.0.so.0 (0x40051000)
        libgobject-2.0.so.0 => /usr/lib/libgobject-2.0.so.0 (0x40081000)
        libgmodule-2.0.so.0 => /usr/lib/libgmodule-2.0.so.0 (0x400b9000)
        libdl.so.2 => /lib/libdl.so.2 (0x400bd000)
        libglib-2.0.so.0 => /usr/lib/libglib-2.0.so.0 (0x400c1000)
        libc.so.6 => /lib/libc.so.6 (0x40125000)
        libfreetype.so.6 => /usr/lib/libfreetype.so.6 (0x40248000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

Notice no GTK, no X, no nothing.

Look at
<URL:http://developer.gnome.org/doc/API/2.0/pango/pango-freetype-fonts-and-rendering.html>,
in particular you should start with pango_ft2_get_context() and work from
there.

Yes.
