If you used a page type it would be much easier than a Editable Text webpart simply because you can query that data very easy with the API or RESTful services. If you use an Editable text webpart retrieving that data is a bit harder and not as robust as using a page type.
RESTful services simply need to be enabled within Kentico with the check of a box. From there you'll want to ensure some security is setup but they are documented well and as I mentioned easy to setup.
