Can you compose a musical piece with a laptop?

I would like to compose a little musical for myself. Now the question is, can you create a song with a laptop?

You can also do this with a laptop.
The question, of course, is how you envision creating it. Because for this you need certain programs that help you create.

If you have the right program for it, then the laptop is enough.

For example, what would one be

A program would be e.g. Music maker from Magix. That already includes small sequences of music that you can put together at your discretion.
Then there's Audacity. A program to record your voice and also insert loops.
