Possibly. Have you decided how you'll be prepopulating the data into the form?
If you want the form to connect to a web service to get that data you'll need RE. If you wan the form to connect to a DB to get the data you'll need RE. You could also use LiveCycle Forms to prepopulate the data in the PDF, but you'd probably have to write a Java webservice that uses the Forms API and call that from your Delphi app, or maybe you can use the .net library, I'm not extremely familiar with Delphi personally.
Basically, I don't see anything from the workflow you've described that would require it except possibly the prepopulation of data, so it depends on how you plan to go about doing that.
