Gnu Radio independent 802.11 based MAC program

Good afternoon,

I am interested to make 802.11 based MAC using Gnu radio. I want to make
at the end an integration with 802.11 PHY implemented using LabVIEW.
Could you please briefly explain if it is possible to make the Gnu Radio
implemented source code independent from Gnu Radio?

Since we want to achieve low latency in our application, please let me
know the achievable latency by implementing the MAC in Gnu Radio?

I have to admit, I am new to Gnu Radio. It would be great to know your
