If you build a wx.App application you can use wx.StaticBitmap indicators
for each channel. The bitmap for each channel can then be SetBitmap() to
either a red or green circle, for example, depending on whether the power
exceeds a threshold. The power measurements and threshold checks can be
performed in a loop/sleep thread. Multithreading with gui applications can
have issues so be sure to use wx.MutexGuiEnter() before the SetBitmap call
and wx.MutexGuiLeave() after.

        you can easily code your own GUI ;). Actually, I find that
        streaming values via UDP or TCP to a remote python application
        works rather nicely. <br>
        And I find that gygtk and pycairo are rather powerful toolsets.<br>
        Also I fiddled around with different python web frameworks,
        taking data from a socket, and &quot;rendering&quot; it by updating a
        browser page using ajax, but I kind of lost interest on the
        way... But maybe this might be of interest to your application
        case.<br>

    YOu can stick a PROBE in the path, and have a static-text box take
    the output of a variable that tells you whether threshold exceeded
    or not.<br>
