Creating a document via an Intranet

I have a project in which I need to setup an Intranet area where a user can select from a list of text sections and have a Word document created out of these text sections and placed in an accessible place or even sent to them. I have developed thesite but I am unclear on any method of how to create a link between these files and a single exportable Word document. I have started the conversion of these small text sections to .html but am not sure that this is necessary. Any help on the creation of this site or a point in a direction where any resources regarding this topic would be very much appreciated.
