Yes you can.
If your 3750G-12 has a flash size of 16 mb then the highest IOS you can use is 12.2(55)SE and later (SE1, SE2, SE3, SE4, SE5 with SE5 being the latest).
As what Reza has provided, the entire stack should be running the same IOS and the same feature set.

Hi,
Yes, you can stack 3750G with 3750E as long as you are running the same exact IOS with the same feature set.
From the Q&A doc:
Q. Can I run Cisco Catalyst 3750 switches with Cisco Catalyst 3750-E switches in the same stack?
have a look:

Hello friends,
I would also pay attention to the default SDM template the 3750G-12S is coming with =>
=============================================
Fixing SDM Template Configuration Incompatibilities (Catalyst 3750G-12S Switches.
The master switch automatically corrects SDM template mismatches in Catalyst 3750 and 3750E switches when you connect one of them to a stack.
A configuration mismatch might occur if the switch was a Catalyst 3750G-12S switch configured with a nondefault SDM template before you connect it to a stack.
•To display the configured SDM template on a switch, enter the show sdm prefer privileged EXEC command.
•To change a Catalyst 3750G-12S switch SDM template to the default setting before you connect it to a stack, enter the sdm prefer default global configuration command.
"or no sdm prefer, then sdm prefer ...."
=============================================
Regards.
