It's a hard work to do. Besides raster image of map you should have some geometric information about geo features shown on map. Map clients ask map server capabilities from map server and then based on capabilities ask layers and geometrical objects definitions. Based on XML vector data asked usually over HTTP client-side JavaScript tracks mouse events and makes highlights etc.

You can find information about GIS standards here: http://www.opengis.org/.

Of course you can use ready software, if you find something that fit your needs. Out there are many map applications.

Also you can write your own client. It shouldn't be very hard to perform as communicating with map server is HTTP based and "communication language" is XML.

To get started find out some map server opened to everybody and try develop for this. Before writing code make sure that server uses OpenGIS standards.
