Our team is in a similar state, with a lot of fairly junior programmers. The first concern is bringing everyone up to speed on the fundamentals of programming, Java, and NetBeans. Later we'll worry about WPILib and the Smart Dashboard.
Something I'm trying this year is a free graphics library from
processing.org, but integrated into NetBeans. This library was created to introduce non-technical folks to coding. It's got a very short learning curve. I'm hoping that it will be more motivating than just having them write "hello world" and basic console programs.
