lattice boltzmann help for 2d display

Hi there I'm in the middle of creating a lattice boltzmann model, now I have all the programming done for the basic model, including lattice, initialization, collisions, basic boundaries, stream function and so on. At the moment all the data is shoved into a .csv file at the end and from there I can manipulate the data create graphs and so on, but what I really want to do is to create a bit of code that will open a window and show a real time representation of the either the stream function of velocity field(both of which go in the csv file at the moment) to show the flow while the program is running.

I'm not sure exactly how to do this, so I was wondering if someone could point me in the right direction or show me an example bit of code to get me going it would be much appreciated

I would use QT (C++) or GTK+(C) for this. There are a lot of tutorials available online that show how to use those two libraries.

Thanks I'll have a look into it

I was also wondering would it be worth looking into open gl or direct2d as its a 2d representation of fluid flow
