srikar - see this tutorial on how to create a GUI using GUIDE, http://www.mathworks.com/videos/creating-a-gui-with-guide-68979.html. Once you have completed the tutorial, sketch out how your GUI should look (you will need three pushbuttons and an axes for your output) and then start implementing the pieces. For the browse push button callback, you will probably want to use uigetfile as your tool to browse and choose an audio file. To play the audio file, you may want to use the audioplayer. As for the FFT, there are several examples within this forum on how to use your audio data, the fft, and displaying the results in an axes.
