Is there a way to create alias without using htacess, permalinks or delving into code?

WordPress core doesn’t have any means of managing redirects by itself. As you are excluding changes in the .htaccess file and adding code yourself, the only remainig option is to use a plugin.

If you search the WP Plugin Directory for ‘redirect’, you will find one very popular one (I sometime use it myself) but there are also many very specialized ones for sepecific use cases.
