This code removes the text from wrapping around the icon displayed

 "warnMsg": {
                        "xtype": "dialogfieldset",                            
                        "hideLabel":true,
                        "hidden":flagHidden, 
                         "html": "<div><img style='float:left; padding-right:10px' src='/libs/cq/ui/widgets/themes/default/ext/window/icon-warning.gif'></div><div style='font-size:12px; margin-left: 40px;'> Your text here</div>",                    
                        "title":"Warning",
                        "name":"warnMsg"

You can use the display field and specify the required output in the html property as shown below.

"warnMsg": {
    "html": "<img style='vertical-align:middle;' src='/libs/cq/ui/widgets/themes/default/ext/window/icon-warning.gif'><div style='vertical-align:middle; display:inline;'>Warning</div>",
    "xtype": "displayfield",
    "hideLabel": true
}
