I suggest you to use GtkTextView for your text output, thank to GtkTextTag
it's flexible enough to do everything a mud client needs, also blinking
text, it scrolls at line boundaries and let you keep thousands of lines of
textbuffer without slowdowns.

For an example of ANSI16 parser/output with GtkTextView using GTK2 you can
look at my own mud client ( source
http://sourceforge.net/p/ggmud/code/HEAD/tree/trunk/ggmud/ ).

I think most of the code you may be interested in is in ansi.c & window. c.
