**Hi my friends I hope you doing well !
as I a PLC programmer, I decided to make my own SCADA inerface and connect it with a PLC ( S7-1200 for example ) or with a programming card ( like arduino ) all depend of me 🙂
I wanna ask about how to start GUI design and programming ? how to start desktop application develpmenet ?
If I need database ? how to start creat it and link it with my GUI app ? and How to connect a GUI app with a device and exchange informations ?**
( I know C++ ( until classes and objects) , some of basic C#, litle of python and Matlab, I just forgot because since 2019 I did not use these languages ! )
