How to implement a winform dialog in Delphi without IDE?

I don't have the Delphi IDE installed. Can I still design forms?

Using Win32: File | New Unit then you have full control of the code.

var
  F : TForm;
  L : TLabel;
begin
  F := TForm.Create(Application);
  L := TLabel.Create(F);
  L.Parent := F; // Needed to have it show up on the form.
  L.Left := 50;
  L.Top := 50;
  L.Caption := 'This is an example';
  F.Show;
end;

In .NET / Delphi Prism: Right Click on the Project|New Item|Class

namespace WindowsApplication2.Properties;

interface

uses
  System.Windows.Forms,
  System.Collections.Generic,
  System.Linq,
  System.Text;

type
  Class1 = public class(System.Windows.Forms.Form)
  private
  protected
    lablel1 : Label;
  public
     constructor;
  end;

implementation

constructor Class1;
begin
  self.label1 := new System.Windows.Forms.Label();
  self.SuspendLayout();

  self.label1.AutoSize := true;
  self.label1.Location := new System.Drawing.Point(37, 80);
  self.label1.Name := 'label1';
  self.label1.Size := new System.Drawing.Size(35, 13);
  self.label1.TabIndex := 0;
  self.label1.Text := 'This is an Example';

  self.ResumeLayout(false);
  self.PerformLayout();  
end;

end.
