The best way to do this, is to set your personnally designed UI file in
the layer properties->field properties->attribute editor layout->provide
Then, you want to call qgis method to show a feature form:
And you would need some processing to show it:
1. get feature id from the selected line
2. fetch the feature of the main layer
3. get the foreign key from one of its fields
4. fetch the corresponding feature
4. show the feature form with it
Anyway, if I understand properly, you're trying to do something which
has been recently added to QGIS (it's in the master version), it's 1:n
