First, set the document orientation to landscape. Insert four text boxes, or insert a 2x2 table -- either will work for this.
In the two boxes or cells on the left, click the Text Direction button (for a table, it's on the Table Tools > Layout tab; for text boxes, it's on the Drawing Tools > Format tab) and choose the option that places the bottoms of the letters toward the left edge of the paper. In the two boxes or cells on the right, click Text Direction and choose the opposite direction.
Type the text you want in each text box or cell, and turn off or reformat the borders as desired.
