I wrote a desktop app (Linux x86, Mac OS, Windows) that lets you program almost all of the demos and applications I've written for gCore without needing to build them first using Arduino or the IDF. It accesses pre-compiled binaries from my website. You can find it in the Downloads section of the gCore page.
The idea is to make it easy to see all the things gCore can do. The only demos I wrote that aren't included are those where you need to include your own Wifi SSID and password in them like the LiFX LED light bulb remote control.
Unfortunately I couldn't sign the app for Mac OS or Windows because the app calls a compiled version of esptool behind the scenes to do the actual programming and I couldn't sign that so the who application bundle couldn't be signed. This means both Mac OS and Windows will complain. On Mac OS you'll have to go to System Preferences->Security & Privacy and tell OS X you want to run the app anyway (you may also have to tell it to allow apps from both the App Store and identified developers). On Windows you may have tell it that the zip is ok to download.
Here it is running on Linux.
And Mac OS X
