You are close. You need to use gtk_widget_modify_font(). You pass in a font 
description created by:

PangoFontDescription *fontDesc =
                        pango_font_description_from_string( "monospace 10" );

This would set the entry text to a monospace-type font with 10 point size. Don't 
forget to call pango_font_description_free() afterwards.

If you wish to change font while typing you need to connect to the 
"key-press-event" signal on the GtkEntry widget and handle key presses that way.
