Hi,
You don't need widgetkit to do that.
One solution we often recommend is to use tags from the plugin Tabs & accordions:
extensions.joomla.org/extension/tabs-accordions/
It's used a lot to do that in Joomla articles and it also work in the description of Hikashop products.
Also, You can actually do that with HikaShop too, with the tabular layout, but if you need custom tabs like this, with different fields, you need a combination of custom product fields and a view override to add the tabs the way you need them.
It's doable even without prior coding knowledge, but you need to follow the instructions in the "How to add a tab in the tabular view ?" section of the FAQ:
