Proposal to create a welcome app for XFCE

Hello XFCE developers,

I am Ajrat Makhmutov, a maintainer of the Linux distribution ALT Linux. 
I like XFCE and want to help make it even better for users.

I have an idea to create a welcome application for XFCE, similar to 
plasma-welcome in KDE or the welcome app in GNOME.
This app could help new users to learn about XFCE and set up their system.

For this project, I would like to use Blueprint. Blueprint is a new tool 
from GNOME that helps to create GTK interfaces more easily. I think it 
can be good for making the welcome app.

I know that XFCE usually uses pure GTK. I want to ask the community if 
it is okay to use Blueprint for this idea. I do not want to make 
problems or go against what XFCE likes. Please tell me your thoughts.
If the community does not like this idea, I can try another way. I just 
want to help and make something useful for XFCE.

Thank you for your time and for reading my email.

Best regards,
Ajrat Makhmutov
