This can be accomplished using SLD. In a WMS GetMap request you can add
an inline SLD using the SLD_BODY parameter, or use the SLD parameter to
point to a URL pointing to the actual SLD XML document.
The Chameleon ExpressionBuilder widget has some code to do this or check
out:

If a WMS layer is queryable, you can perform a WMS GetFeatureInfo
request against it using an X and Y value in pixels, which can return a
plain text, HTML or GML document.

Hi all, i have a question in WMS, can a polygon be hightlighted in a
map in wms server, like can anything be included in the url that makes
a certain polygon marked, for example i want the border of the polygon
to be highlighted .... i was able to do it in mapscript but was
wondering if the same thing can be done in WMS ...
one more thing, i am not pretty sure what query layer does in wms ...
Thanks for your time
