custom database to printout

I would like some software developed which allows me to manage a small database. The database entries would consist of an object ID, an image, and several strings, all except the ID being optional. The software GUI would allow input of new records to the database, with manual entry of strings, and selection of a image. The software would also allow viewing/printing of any entry in the database. The viewing would be via a selectable template. The template describes the position of the image and text strings on the output page, and also specifies the page size. Specifically, I want to print database entries to envelopes of various sizes. I would like to specify a list of records and have them viewed/printed successively (i.e., type 1-10 and have records 1-10 displayed, or 1,3,5,10-20,144 to show those). The software may run on Linux or WIndows, using any language. I would prefer use of a Postgres database, Java, Python or C/C++ and Linux but am open to alternative approaches. So I see the tasks being: 1) database tables 2) template(s) -- can be text-based files for simplicity of implementation (this is an infrequent task) 3) GUI for data entry (picture/strings) 4) GUI for data display (using selected template) 5) Printout capability There may already be existing software to do this sort of thing. All source code required as a deliverable.
