Formula To Reference Rows Across Columns

I have two workbooks open, Workbook 1 (W1) & Workbook 2 (W2)

W1 has the following data entered in about one of our clients:

A1= Client Company Name
A2= Client Name
A3= Client Address
A4= Client Phone Number

What I would like to do is the following:

In W2, when I enter (in any cell, but let's say C3 for example) that C3 = A1 (from W1), that I can automatically have the following cells D3, E3, & F3 filled in with the same information appearing in cells A2, A3, & A4 from W1 as well.

I believe this must be possible-- I just don't know the right formula & steps to take, to make this happen.
