(Newbie) Is there possible to create dialogs with blueprints ?

Hello, I am pretty new to Unreal Engine, as I am just learning the basics, I am also wondering if there is possible to create an blueprint of dialogs ?
And if it is, do you guys know any good place to start ?

Yes you can create whole dialog system, but it is not trivial, better start with simple stuff. At least learn blueprint communications first.

Best place to start is google and tutorials for unreal 4.
