GDK_USE_XFT won't matter if you are on Win32. :-)

Whtehr you are using Win32 or are using Xft,
gdk_font_from_description() is not going to work. It's basically just
a hack to get a little bit of interoperability between Pango running
on top of X fonts, and GdkFont, which is basically a thin and somewhat
screwed up wrapper around X fonts.
