need help creating text window

I am writing a telnet application (the telnet stuff is done), that has
a window that is updated with the text coming in from the telnet
connection.  I need a scrollable window that can have ansi colored text
put into it.  I have tried it with a memobox and cannot figure this
out.  Doesn't appear to be able to do it.

In other words, I need a scrollable window, that has lines of text
in it, that can have different ansi colored characters on it.

Has anyone done anything like this?

Thanks in advance!
