You should install WordPress and create the homepage.
You can find info about that.
You can use the deafult layout without programming.
Then you must look for a plugin that creates a login page, like Plugin Theme My Login.
For WordPress you yourself login as administrator, but you can create more users with less rights. They can e.g. write to a page or only read. Your complication is that a doctor and a patient must look at the same page. I’m sure there will be a plugin. Just look on the internet for WordPress, plugin and check it out.

Do you get an error message? I remember I had a message showing the temp file couldn’t be created.
I found a solution on http://ww.wp.xz.cn/support/topic/pclzip_err_missing_file-4-missing-archive-file-cwindowstempwordpress-3
I had to enter a line to wp-config:
define(‘WP_TEMP_DIR’, ABSPATH . ‘wp-content/TEMP’);
and then I could install plugins again.

You can make a copy of the php you work with and place it in the themes folder. Or better make a child of the thems folder so it won’t be overwritten with an update of the theme.
Then in the copy you change the title:
<?php
/*
Template Name: new name
*/

In this copy you remove the oce that creates the header. This depends on the theme you use. It might be something like

<div id=”gazpo-nav”>
<?php wp_nav_menu( array( ‘container_class’ => ‘main-menu’, ‘theme_location’ => ‘header_menu’ ) ); ?>
</div>

And you base the pages that don’t need the header on this template.

I don’t know exactly if this hleps, but maybe you must look the other way, so not grandchild but grandparent. I used this for showing titles:
<?php //variables
$grandparent = $parent->post_parent;
$grandparent_title = get_the_title($grandparent);
;?>
