Hi Elena,

For windows form, you need a button after which window form will be pop.

Example :

 xtype: 'button',
                            text: 'Register',
                            listeners: {
                                click: function() {
                                  
                                   Registwin.show();
                                }
                             }

Here is the code to create windows application in Sencha ExtJS. Please review it and let us know if any updates are required.

 Ext.onReady(function () {
                   Registwin = new Ext.Window({ // Creating login window 
                       xtype: 'UserForm',
                       modal: true,
                       closeAction: 'close',
                       layout: 'fit',
                       height: 300,
                       width: 400,
                       title: 'Register',
                       items: [
                           {
                               xtype: 'form',
                               bodyPadding: 5,
                               items: [
                                   {
                                       xtype: 'fieldset',
                                       title: 'Fill The Details',
 
                                       defaults: {
                                           xtype: 'textfield',
                                           labelWidth: 100,
                                           maxLength: 10,
                                           enforceMaxLength: true,
                                           width: 300
 
                                       },
                                       items: [
                                            {

                                               enforceMaxLength: true,   // Used so that user cannot enter the value whose text length is greater than 10.
                                               allowBlank: false,            // Putting validation so that this fieldwill be manadatory.
                                               msgTarget: 'under'         // Place Where we need to error message. 
 
                                           },
