I want to create an icon on the normal desktop for email with an unread email counter and when clicked it should open Claws-mail. The Gmail script from the wiki doesn't seem to work (anymore?)

I have managed to get something with curl in the console using the command from here 9adding -k option but have no idea how and where to fit this as script in qbw.
I think it can be done in a script like mentioned this. but exactly how to do this I don't know
Is this possible? any idea's/help ?
