SMM landing page with Wordpress

Hello,
I'm a beginner so I need your help.
I installed the Smartpanel script but I don't like the design of the landing page and I don't have much experience with css to change the design.
That's why I have the idea to use a website builder like WordPress with Elementor.

Is it possible to keep my SMM panel script on my current server with Cpanel and the landing page on Wordpress?

example.
http://www.smartpanel.com on wordpress (landing page)
http://www.smartpanel.com/login (login page) and smmpanel.com/order (order page) sub directory

Is this possible?

Thanks in advance

I supposed if you put wordpress files in the root directory like this

public_html/wp-admin/
public_html/wp-content/
public_html/index.html

Click to expand...

and your script files in a subdirectory like this

public_html/yourscript/login/
public_html/yourscript/index.html

Click to expand...

it could work. People will end up on the wordpress landing page when they go to http://www.yourdomin.com and you can redirect them to http://www.yourdomain.com/yourscript/login or whatever as you need.

Yes you can do that
I can help you with the design changes and the landing page on WP at once
