Preferred language for creating apps for PinePhone

[evilbunny]

Hi all, I've ordered a BraveHeart and am looking forward to playing around with it.  I'd be interested in creating some simple apps for it and wanted to get people's opinions on what language people will probably use to create apps for the PinePhone.  Most of my programming is done in Python but I wonder if many people will consider Python to be too resource-intensive for a fairly small and low-spec machine like the PinePhone, perhaps going instead for something more minimalist like Lua or even C++ would be more appropriate.

I've done a little bit of development for Ubuntu Touch using QML and Python. I'm told UT is the most advanced app wise.
