Creating an Offline Web based Map for GPS tracking

I am currently on an aviation related project which requires an offline web based map. I have been looking for a step by step procedure on how to host an offline map that will be used on an offline web portal. The project requirements are : 1. to be able to establish a fixed zoom offline map. 2. plot and track using lat/long values from sql database 3. able to accomplish this requirements on a windows os.

Currently I have been able to pull lat/long values from a gps receiver and save them on a database. Hoping to have someone direct me to where I could start. The offline map does not need to be very detailed and should show minimums such as Country name and major city.
