Developing for PinePhone

[macias]

Hello,

  Sorry for naive question, but how will developing for PinePhone look like? (I don't have it right now). Is it like regular Linux, so the screen is treated as monitor, I have to use Gtk, etc? Or there is needed extra framework for it?

  I have in mind such tasks as:

• building and showing screen/windows with button, labels, textboxes,
  
• subscribing for GPS position update
  
• waking up phone and showing my screen
  
• forcing phone to turn off the screen
  
• running some processing in the background (like a service in Android)
  
• querying battery status and charge level
  

Thank you in advance.

Cheers,
