I am to develop an application on windows. I have never done that before 😉

I need to do some heavy audio calculation, which has to be written in C/C++. This part will be a room correction algorithm which currently takes about 10 seconds per channel to run in Matlab. It has to be written in C/C++, since it might be ported to a DSP later on, which has to be programmed in C/C++.

Additionally, I need a GUI to review calculations, visualize results and modify calculation parameters. The tough part of this GUI will be lots of plotting of spectra, spectrograms, audio waveforms and the like.

Now, I hear that WPF is all the rage in Windows GUIs, but it seems to be limited to C#. Is there a simple way to integrate my C/C++ code with some C# GUI code? Or should I rather take WinForms and just write the whole thing in C++? Or would Qt work just as well and provide some cross-platform capabilities “for free”?

I have some experience with C/C++, Matlab and VST-development, but I never wrote a real application and honestly, I don’t even know where to start.

Thank you in advance!

    I think the biggest drawback to using WPF or WinForms is that you will have to program in two programming languages, which is a big logistics overhead.

    I’ve seen this type of argument before: use C or C++ for low level, something else for high level. In this case Qt/C++ is as high level as WPF/WinForms, with the benefit of very easy integration of UI to your other C++ code.

    For spectrograms and other graphs check out Qwt.

    P.S: WPF is not all the rage on Windows, in fact the market is quite fragmented and WPF is one of the lesser used GUI toolkits. Most of the code out there uses MFC, WTL, Delphi, Win32, etc.
