I've always just done this with TileCache:

Do you really need WMS? It's possible, but I'd have to write some code,
and I'm very lazy :)

Open any modern OpenLayers page.

Open Firebug. (Or just open
http://openlayers.org/dev/examples/debug.html , which has firebug lite.)

Type the following:

 new OpenLayers.LonLat(-71,42).transform(new
  OpenLayers.Projection("EPSG:4326"), new
  OpenLayers.Projection("EPSG:900913"));

Get result:
lon=-7903683.845222223,lat=5160979.443331368
