GUI for Stetl ETL Execution

[justb4]

Several requests for "a GUI for Stetl" were made. There are two GUIs to consider:

1. a "construction GUI" to create Stetl Chains, i.e. a Stetl config file
2. an "execution GUI" to execute the actual ETL (based on Stetl config file)

The first would require a tool "FME-like" to draw Inputs, Filters and Outputs and connect and paramterize them. The second is easier: manage the execution for a single Stetl config file. This issue adresses only the second/execution GUI.

Requirements

An initial set of requirements:

• cross-platform (Win, Mac, Lin)
• easily (un)installable (installer)
• minimal scenario: choose ETL config, parameterize (e.g. inputs and output parameters), execute

Secondary requirements:

• prepare for becoming a Cloud service

Implementation options

• cross-platform Python GUI framework like PyQT, WxPython etc
• Webtech cross-platform: Electron or lighter: PyWebView: https://github.com/r0x0r/pywebview
• Jupyter-based: https://github.com/r0x0r/pywebview ? (GUI via websockets)
