I'm no expert either.

I guess you will have to create a component that reads in the values of the FFT and then finds the maximum magnitude. You can then multiply the time-step of the maximum value by the frequency per bin and you will have the frequency of the largest component.

To do this you will have to write some HDL or use a tool like DSP Builder.
