Creating a wire from array of coordinates

I am just getting started writting my first OpenCASCADE application. I would like to create an application that would get an array of doubles and then it would create a wire connecting the points in the array. I have looked through all the examples and they assume that the number of edges on the wire is always known. It seems that one could do this several ways but I would like to know what the best way of doing it is. Since I am not very familiar with OpenCASCADE, I would appreciate if you could give a small code sample.

Thanks
