Minimum salary to relocate a 4 person family in Zurich

Hi all,
I'm  new member and would like thanks everyone who can help me to have some information about salary in Switzerland.

I received an offer that is 110.000 CHF (gross).
We are 4 (me, my wife, child of 2 years, and a daughter coming soon).

Here in Italy we work both but moving to CH my wife will stay at home with the children, at least for a couple of years.

So I need your help to understand if with my gross salary, I can afford a comfortable life with my family.

I do not mean to "waste" money when I say comfortable, but for example I'm thinking about:
- 2 bedroom apartment (outside Zurich 20/30 Km, moving by train to go to downtown)
- 1 car
- having a lunch outside with my family once a week

Thanks to all in advance.
Valentino
