Vista - Need to programmatically color words in text editor

I want to create an application with program script editor that supports
syntax color highlighting similar to the Visual Studio editor.
I need a way for me to tell the text editing control to change the color of
a number of characters of text at a particular character position.

What is the best way to go about doing this in WPF?
I looked at the TextBox and it doesn't appear to support this.
I took a quick look at the RichTextBox and I don't see any way to do it
easily with this control either.
Should I create my own control derived from TextBoxBase?
Thanks for any help you can give

use TextRange.ApplyPropertyValue(Inline.BackgroundProperty, Brushes.Yellow);
