I am new to web development, my friend ask me to help in developing a website for her company.

Her company business nature is about dance and interactive art

If I use wordpress, could it be suitable?

It's going to be really challanging for anyone to advise you based on the information you have provided so far. The only advise is that using a CMS solution like Wordpress will make it easier for managing the content especially is web development is not a strength. Now if Wordpress is appropriate for the requirements is something you will need to investigate in more detail.

Set up a Wordpress site and give it a try.

I would think a CMS is an overkill here since you can just work with a provider to set up a website from a template that is meant for a site with a few pages of static content. That would cost just a few bucks per month and your client can be up and running by the end of the day.
