I've made cabinets that were perfectly airtight with makeshift clamps like weights and braces. But I'm pretty sure any self-respecting cabinetmaker would frown upon that.
Screws are fine as long as they don't split the wood. Drilling the hole first will help a lot. Put a small dab of glue down the hole and only tighten snug - all you need is a little clamping force. That will hold the panels in place, which is all you need them to do.
