If you don't need font or color changes, you can do all this using a Text
widget very easily [in Motif 1.1, anyway].

        loop() {
            pos = offset_of_pattern_in_text_widget(pattern, text_w);
            search_len = strlen(pattern);
            XmTextSetHighlight(text_w, pos, pos+search_len,
                        XmHIGHLIGHT_SELECTED);
        }


There are two choices for highlighting: reverse video (HIGHLIGHT_SELECTED) and
underlined (HIGHLIGHT_SECONDARY_SELECTED).  Be careful that your users won't
confuse your highlights with actual selections!
