+1 for Wails mention: just discovered it recently which brought me to Svelte--couldn't be more impressed. Golang "backend" w/ a Svelte "frontend" to build desktop apps the fraction of the size of Electron is a killer imo.
We do a lot of data/quant analysis w/ Go which is great for that; then having the opportunity to slap on a lightweight GUI allow us to make some great internal tools etc.
