My guess is that this is going to be way beyond your skills.

A GIS is an extremely complex system to build. If you have the map already built, then you would just have to get the coordinates under the mouse and then compare those coordinates with the coordinates in the database.

If the database contains points, then you'll want to include a buffer around the points because the chances of the person clicking exactly on the point is pretty slim. If it's a polygon, then you just need to check if the user clicked inside the polygon. But if it's a complex polygon, determining that can be quite difficult.

My suggestion is to simply create a KML and load that into Google Earth or create a Google Map online instead of trying to build a GIS.

But if you really want to build your own GIS application, then look into getting a subscription to the ESRI developer's network which will provide you with API's already written for the top GIS program out there. Then, you'd just have to purchase an ArcEngine license for any machine running your application.
