You might take a look at the (non-commercial) site for
NOTAMPlot, though this might make it
too easy!
Hyperlink preservation note: it really is non-commercial. From the Web site: "NotamPlot is free! However if you find the program useful I would appreciate it if you would make a donation of at least 10 UK pounds to a charity of your choice in exchange for use of the program. The software is available to all as a gesture of goodwill after much development effort. Please reciprocate this goodwill with an appropriate donation."
