Is WordPress the right tool for this?

Hello

I am using since several years drupal and am considering now to switch to wordpress, because wordpress has several new features compare to a few years ago.
I have several websites, some are blogs or news sites, some are more complex. My question is about the more complex ones.
Example:
I have a site for sport courses. Companies can register and offer their courses there. I have custom content types (post types?) with custom fields, e.g. for company:
– name
– address
– description
– website
– selection from a list of tags
e.g for courses
– name
– description
– type of course
– location
– date
– link to company this course belongs

On the website it is possible to browse by state or city and get a list of all offered courses. Or to filter by a specific type. Or to search.
When the user clicks on a company, he sees after the company information a list of courses this company offers.
Also I want to create custom views.

As you see I need
– custom content/post types
– possibility to establish relations between them
– custom views

I was searching the forum and the internet. As I understand, this is in principle possible. What I don’t understand, whether this is easy possible with a plugin/widget and no coding required. Because I don’t want to code. For example I found the plugin subposts (www.subposts.com), but I did not find it on wordpress.org with its thousands of plugins/widets.
I am overwhelmed by the amount of plugins/widget, but I am not able to tell whether it fits my needs really.

My requirement would be to have a plugin/widget, which is stable, according wordpress guidelines (no hacks) and used already quite often.

Any feedback and help appreciated,

thanks
