Well, JGNP doesn't exactly have WEU included. But it offers the option to integrate it into JNGP in case WEU is already installed.
Also the trojans that some antivirus tools are reporting are false alarms. Unfortunately, due to how JNGP works, it can easily be mistaken as a virus, when in fact it isn't.
Lastly, JNGP should work with the latest patches as far as i know, because the 1.21 wordedit.exe is included in recent versions of the pack. The only problem with 1.23b is that because the return bug got removed in the update, you'll have to wait for a version of jasshelper, that doesn't use it.
