Catalan move order

A question for the more advanced (Catalan) players here, but against 1. d5, how should you still achieve your Catalan setup? Should I play nf3 and g3 first, or should I play c4 and try to go into the Catalan in a Queen's Gambit move order? I've noticed that if I play nf3 first, a lot of people will play nc6 instead of nf6, and if I play c4 first a lot of people will play the Queen's Gambit Accepted and then I can't really go into a Catalan

play c4 first o_0

depends on taste. I'd play g3. Nf3 Bg2 and then play c4. 

so you're saying 1. d4 d5 2. g3 ?

Nf3 then g3 would be a better move order because colle ;)

oh ok thanks
