Yes, Vegas can do this. Use one of the batch rendering scripts from the scripting forum or on the Sundance site. Another option would be to purchase "Batch Render Pro" at http://flash.to/rmtools/
For the BatchRenderGUI script there really is nothing much to daunt you... as you basically just have to run the script... then a prompt windows appears where you select the formats you want to render to and leave it do it's stuff. Simple... I think.
What in particular do you find to be daunting? You don't actually have to look into the script at all.
Or... maybe I am assuming you are wanting to render a single veg to multiple formats... but perhaps instead you are wanting to render multiple vegs to a single format?
The latter thing does require going into the RenderQueue.js script to manually enter the name video template to use.
I agree... for a "non-technical javascript comfortable person" that would probably be a little daunting.
