Not open source = not at all like WireShark, sorry.
And that's a damn shame. I could see a community growing around this kind of thing and adding all kinds of protocol support to it, if only it was open source.
No competition with WireShark is intended. WireEdit is a packet editor, not an analyzer. Can as easily edit a .txt Hex dump of a packet (not yet supported, but easy to do).
I will admit that I initially thought this was a Wireshark plugin or related to Wireshark in some fashion, based on the name and the appearance of the GUI on the page.
You may want to put a little disclaimer at the top saying it's not associated or competing with Wireshark.
If you're concerned your NTP servers may have the monlist command enabled and therefore be available for attackers to use to mount these reflection attacks there is a Nessus plugin to check for this: http://www.tenable.com/plugins/index.php?view=single&id=7178...
