Using the timetable noted by Lucas, you'll see that you have options on where to stay Saturday night.
Rockoyster's suggesttion is a good one....Zürich Flughafen is 1 hr and 3 minutes ( direct, via Zürich) or 1 hr 7 minutes ( via Zürich/change at Zürich). And if by some chance you miss the connection at Zürich, there are lots of trains every hour from Zürich main station to the airport.
Even if you stay in Wengen, you could catch the 0803 on Sunday morning and arrive at the sirport at 1116
I assume that you are not traveling in November, when I'd be a lot less likely to go to the Jungfrau region.
You could spend many days in Luzern, and both Titlis and Pilatus ( quite near to Luzern) offer high Alpine experiences.
