tooltip for WMS points with geoext

Question

My idea is to get tooltip contains information about the point , these points return from WMS layer, i tried these ways:

1- with vector layer there is "graphictitle" when styling the points and it display a tooltip, but with WMS i could not find property to use it as a tooltip in SLD(wms styling).

2- when i use ext tooltip , its return wrong location because i don't know what the target .!

new Ext.ToolTip({
        target: 'no target',
        html: 'A very simple tooltip'       }).show();})

3- so i want to use geoext .

can any one help ?
