Programming curriculum for elderly students
If the students in this course are the same ones, or similarly educated, that finished the last course, you could be over thinking the issue. They don't yet have the exposure to know they want to become programmers.

Design the next course as an Introduction to Programming. To borrow from the course catalog for KCTCS pg. 253:


  Computational Thinking
  
  Promotes understanding of computer programming and 
  logic by teaching students to think like a computer. Covers 
  skills needed to develop and design language-independent 
  solutions to solve computer-related problems. Covers 
  development and design basics including use of variables, 
  control and data structures, and principles of command-
  line and object-oriented languages.


That should give the enough knowledge to choose programming as a second career if they want. As an alternative, you could do web page development. That gives a faster return on their work, and allows you to also cover programming using JavaScript. Web page creation is something that more of your audience can potentially utilize in personal life, without having to make a career out of it.

As a third course you could get into the theory and "nitty-gritty" of programming.
