I would think a simple, 2-column table will be your best bet. Depending on your requirements, I would start with not setting a specific row height for any rows, but uncheck the default "Allow rows to break over pages" on the Row tab of the Table Properties dialogue. This may help keep related left- and right-hand material together better.

Note that table borders can be made invisible by selecting "None" in the Borders and Shading dialogue.

Best,
