FYI there are many options.
As mentioned, there are many freeware and payway programs that can add, not only vintage aircraft, but vintage scenery as well.
If you're the sort who likes do-it-yourself programs there are also many freeware design and traffic programs available.
Personally I like "free stuff" and am lucky enough to have some time so I use ADE9X which is a freeware airport design package. For me it's a lot of fun, once I got the hang of it.
For traffic I use TTools, which is also freeware and you can add just about any add-on or default aircraft you want, set up flight plans, and even have various aircraft doing touch and goes at your airport. (when I say almost any aircraft there are add-on aircraft that don't work at all or perform poorly as AI aircraft) I've found that those are very few though.
Those are only a couple of my personal favorites.
As example, pictured below, I now have a combination of vinage and modern aircraft flying in and around an airport located locally to me, and also, another airport where I recently added some parking spaces and flight plans using the two programs mentioned above.
Once you get the hang of it you get faster. The changes to I made to FAPY and the added traffic only took about an hour. I'm still not very fast....the changes to 8G7 were done in the beginng, as I was learning, and took weeks. 
I'm, by no stretch of the imagination, a computer guru.
By checking out the defaul airports, it will become obvious, of some of the changes I've made
8G7 ( added and modified the taxiways, some buildings, moved the beacon, etc. to make it more like the actual airport)

FAYP (added parking spaces and a grass taxiway)

It is obvious that I'm very much a beginner, and neither a scenery designer nor an expert with the programs. 
I hope this helps
