Not that I know of.  The reason this isn't possible is that a reverse
video selection would give the same appearance as if the text were selected.
And you don't want to go messing with the selection mechanism.  You can't
change the font for "portions" of the strings, either, so don't try that.
You can change the font for the text's value itself, but to do that, you
change the font for -all- text items in the panel.  And you can only affect
that at panel creation time, I believe (I may be wrong, but it doesn't
matter -- you shouldn't do that anyway).

You should consider using other visual cues such putting up a notice
that eminates from the text you want the user to notice.  This is in
fact what I do when I want the user to be aware of mistyped or wrong
text values for certain panel items.

| | Ok |                      \                      |
| +----+                       +----------------------+
+------------------------------| This value is wrong. |
			       +----------------------+

In this situation, when the user hits the Ok button, I check the
settings of the panel sequentially and when one has an invalid
value, I put up a notice like the one showed above.
