well, there's two routes you can go down.
you can attempt All Grain or extract.
theres a lot more options when you malt your own.
you can get GF extracts, ive used sorghum 45 DME from breiss as well as their tapioca 45 DME.
i did a quinoa all grain brew for my first batch.. came out awesome.

malting the quinoa was really easy (as in not complicated) and fast. i reached what i thought was full modification following 2 days soak time and 3 days germination time.
i agree with icasanova, check out the malting sticky.
i might also suggest dedicated primary and secondaries for your GF brewing.
