Creating a user interface

[nripun]

I am creating an audio processing application with all the popular classical filters for sound analysis.
My problem is to create an interactive graphical user interface where i can display the sound waveforms , time-vs-freq graphs , spectrogram etc in a very colorful way.
Where do i start. I have good exp in VC++6.0. Will it be easier to use VB to finish this task.

GDI can do the job.

VB would be easier, but processing audio requires speed. You may write the front-end in VB, and write C++ dll's to do the heavy work.

You can download trial versions of most of the popular apps, so I'd look at some of them, and see what their GUI's look like.

Can i use DirectX to design the interface in VB?

Sure, if you mean that you want to call DirectX from VB6.
You'll find a lot of sample code here:
