After having installed gpg4win-2.1.0.exe, this is a Windows installer which installs everything that seems to be needed for this. The default is to have GnuPG checked. The other tools have been unchecked. When the GPA is checked, this provides an interface to read a key and extract a key ID and some related information in regards to the key.
There is also this link which provides some gpg command line utility information:

However, for the GPA tool, in order to obtrain the key ID, it is not clear if there is a way to automate that. So, basically, the way I understand it, everytime we will receive a new public key, we would have to go in the GPA interface to get the key ID. Then, we would be bale to use the command line to encrypt our file.
Any more information in regards to this will be welcome.
