How can I add my own (custom) widgets to Jet

Hi all,
Do you now how to add our own widgets to Jet?
I wrote my own widgets but I could not able to install it to the phone.

I tried web, i put .wgt file on web and tried to download it from Jet's web browser, it said unknown content.

I tried tkfilexplorer and put widget directly to phone and it didn't recognize it.

Could you please help if you know any way of how to put my own widget on Jet.
