Start with Glide. Once you feel comfortable with Glide, move on to Zapier. Then learn a little bit of Webflow and try to combine it with Zapier. And finally move on to Bubble.
I personally adopted the opposite approach and began with Bubble first. If I had to do it again, I'd begin with Glide.
Try glide apps. As long as you know how to create a simple table in Google Sheets, you're in safe hands. Glide will create an app out of the box which you can customize.
