I need to write a simple application for the MK20DX32 that I have put on my custom hardware. I do not have a tower system or freedom system.
Is there a basic project template or sample code the K20 that I can use as a starting point?

This can be built with the IDEs listed here: http://www.utasker.com/kinetis.html
For your chip you just need to adjust to the corresponding linker script file, whereby you can add your own HW simulation model if you like and work with VisualStudio (free VS2013 express version is adequate).
