Delphi is it possible to put a GUI in a dll?

Question

Delphi

Is it possible to put a form made in Delphi (or even better Lazarus) into a DLL?
Those. for example, the form1.dll library from which you can call something like Form1.Show(); etc.
I am also interested in options where non-VCL components (LCL) are used, I understand that now, probably, Qt can come to mind .. if you have a good book on its use in delphi or wxWidgets or their analogues, I will be glad. But I need something more compact or something. Since it is planned to use only a couple of components in this library (in which I am going to put the form).

Answer 1

easy, you can even shove the exe file into a DLL

Answer 2

You can, for this you need to:
1) Create a dynamic library project and place the necessary forms in it;
2) Design an interface (or several) of your library, whose methods will allow you to perform "something like Form1.Show ()";
3) Write a class that implements the above interface;
4) Write an exporting function, which actually returns the library interface.
Just in case: Keep in mind that using the form in the dll you drag the entire VCL with you, maybe the task statement itself is not correct?
