Todd,
You probably are. Json is pretty simple text and the widgets are just part of a arrays like
"widgetsOnScreen" : {
"widgets": [
{
"position" : {
"left" : 105,
"top" : 45,
"relative" : "map"
},
"id" : "_6",
"name" : "Query",
"version" : "2.4",
"uri" : "widgets/Query/widget",
"config" : "configs/Query/config_Query widget.json",
"icon" : "widgets/Query/images/icon.png"
},
