How to register a DLL using a custom registration system and view PE executable files for imported DLLs?

I want to write a C ++ program that does the following

input executables

Output yes / no

condition:

if (if all the dlls imported by my executable are registered on my system)
yes the
rest is
no

so I need to know
1) how to write a user registration system that can allow DLLs to register and track registered registered

2) how to look at my input files in PE to get imported DLL information
3) how to check the condition suggested above
