What you need is

Gtk::Widget::create_pango_layout(const Glib::ustring& text);

You can pass the returned Pango Layout object into

Gdk::Drawable::draw_layout (const Glib::RefPtr<const GC>& gc, int x, int y, 
const Glib::RefPtr<const Pango::Layout>& layout);

to render the text.
Gdk::Window inherits Gdk::Drawable so you can get the
Gdk object representing the screen area of the widget
you want to render the text into with

Gtk::Widget::get_window();
