Read guild/general chat without WOW GUI

Hi everyone,
I was wondering if there is a way to read the Global chat /Guild chat programmatically without using WOWs GUI. As you can see my PC is kind of a "potato", and logging into a busy dalaran is quite costly on it's performance, and the well-being of my ears.
Personally i tried to establish a connection with Warmane's wow server using the WOW TCP/IP protocol but was unsuccessful. I am getting stuck on the CRC hash of the CMD_AUTH_LOGON_PROOF_client because apparently Warmane uses a different type of data structure than the one on the documentation.
Now, can any dev walk me through their login process? or is there a way to querry global/guild chat without going the through the Wow login headache?
Thank you in advance.
