Using Orchard CMS is it possible to build an interface for fast list entry?

I'm digging into orchard CMS, but I'm a little bit skeptical that I might
not have the ability to do something like create new content items quickly
without posting back to the server.
For example. Let's say I define a content type for a product. One property
a product might have is a collection of variations or similar products
that can maybe be sorted by relevance. (Think a comic book with variant
covers)
Could you build an interface for this where you enter a new product, and
search for and include multiple variant products all from the same client
interface without ever having to post back or do a hard page refresh?
I guess maybe, what I'm really asking is if it would be easy to expose the
content through Web API or something like that, and from there you can
really just build anything.
I'm a little worried about starting down the road of using a nice
framework like this, only to find half-way through that I'm limited by the
framework itself.
