Check out this section of the manual; it's got an example for you.

http://buildbot.net/buildbot/docs/latest/Triggerable-Scheduler.html#Triggerable-Scheduler

I'm a novice too, but following that example was pretty easy for me.

In short, I think you'll make one new schedulers and one new builder. 
The scheduler will be a Triggerable and will have a builders attribute 
of all of your existing builders you want to run. The builder will just 
have one "Trigger" step that activates the new scheduler.

(This can makes a couple other things nicer too: if you have other 
schedulers that you want to trigger builds on all configurations, say 
one that watches for changes and one that does it periodically, they can 
just use the new builder name instead of listing out all the 
configurations again.)
