Hello forum!

Yes it is possible.
Short tutorial:
1. Create your widget on PC, with hotspots and link it with corresponding shortcut core ( like in jimking`s tutorial "HOTSPOTS Part3: Assign an application" ), just ( in my case ) it worked with "!open" selected in Event, OnClick action (with !ShowSetting selected i had a "loop" effect... strange...). In any case try both and see what works.
2. Save your widget, copy it to android and run it. For the 1st time click on your hotspot, chose your app, done. Every other time you clicked on that hotspot your app will run.
3. Now the IMPORTANT part! Assumed your device is rooted...Go (with ES or RootExplorer or...) to data/data/com.xwidgetsoft.xwidget/shared_prefs/. Copy "widget(some number).xml" file to usb or sd card and transfer that file to PC.
4. On PC open that xml with notepad++ or some other editor.
You will see correct shortcut ("in path string") started with "#intent;act..........;end" .
Copy that shortcut. Open your widget in xwidget editor and paste to Shortcut Path in Shortcut Setting.

Display name field will appear automatically.
Save widget.
5. Reinstall xwidget (optional) , delete your "old" widget. Copy your new widget to android, test it. Now your shortcut works
instantly.
6. Enjoy
