How to create a simple GIS in c++?

Question

C++ / C#

I have a task to develop an application that will solve the problem of working with a real map. On the map there will be an object from which the shortest path will be drawn to the address that we enter.
From the knowledge I have only knowledge of c ++ (syntax), tell me how to solve it, shoveled the floor of the Internet, did not even find a hint of it, I thought to use Qt, but the task should be solved in c ++ with 0

The first thing to know is which GUI libraries/frameworks can be used (Qt, wxWidgets, GTKmm, MFC, etc). If not, then suffer and curse the teacher.
If so, then write an image viewer first - create a window with buttons on which you can draw a picture, scale and move ( BitBlt- our best friend). Then associate with the picture-map the route points, on top of which you can place a graph of possible paths. And look for the shortest path using Dijkstra's algorithm.
There are sources for such a thing, but on Qt, I can share it.
