Dear Awoke, 

Please find in the link the Cochrane free software to conduct a meta-analysis.

RevMan, Openmetanalyst, MetaXL are relatively easier. 

Comprehensive Meta-analysis(CMA) is user-friendly but you have to buy it. There are also many youtube tutorials for this software. You can easily learn it. 

Powerful: STATA or R.

I recommend you to use STATA. 

I hope it works for you...
