Are you sure? I started building a desktop application recently. As much as I abhor Electron and refuse to touch anything built on top of it, there basically wasn't any other choice due to the absolutely massive amounts of libraries written for the web. I threw a couple of them in and it saved me at least 90% of work compared to what I would have to do if I'd chosen Qt (or anything else native). Would I rather spend a week and have something to show to my client, or roll up my sleeves and re-implement everything myself (which would take about half a year before I'd have anything working at all)?
(For the record, I didn't downvote you. I consider it a shitty practice to downvote somebody for their opinion, without even replying.)
