Simple Letter - Word or Google Doc

Is there any app, Podio connection or otherwise that will allow for simple in Word or Google docs?

Basically, if I wanted to write a letter by clicking a single button in Podio, and it auto-generated the letter for me to print and send using information already stored ( ower name - address of the property )  in a Podio record, what would be the best way of doing that?

Many thanks,
