Digitalk's Smalltalk V was pretty good at this. You got a nearly empty v.exe file which called a bunch of .dll files which contained the various parts of the standard image. Anything you did yourself would be added to v.exe so when you were ready to ship you just had to send the client that plus a subset of the .dll files (enough for your application to run, but not the development environment). For a short while in the 1990s Smalltalk V/Win was available at no cost with the name Smalltalk Express.
