I would like to introduce my new project walv.  You can try it online.
walv supports C and Python and has many features(style editor, code preview…). It’s a static web app and can be deployed anywhere. To use walv, what you need is the latest browser(Recommend PC 1920x1080).
Style Editor(initial, for text only)
Usage
Create
- Click a node of the treeview in the left(as the parent), for example, screen.
- Choose which widget you want, and then click the +.
Generat && Export the final code
- Click the Generatebutton to generate the source code, you can preview and edit the code in Code Editor.
- Click the Exportbutton, you can download the code in Code Editor.
This project welcomes any suggestions and ideas.
