Making a software from scratch

Question

Hello everyone
New to programming.
I need to make a software (gui plus excel data in backgro) which should be used by some users without having them installed any IDE to run it. So, I must give them an executable file or any url that they can execute in their browsers or execute by other means.
I need suggestions where to start from. Which language to select and other helpful advices. Will python be fine. Need to make every module expandable so that they could be added with more functionalities later on..
Thanks in advance

Answer 1

for browser as gui you need usually HTML/CSS/javascript
for excel data python is ok,
with python and some framework you can create GUI too
