+= PJWIN - Portable Mobile Windowing Toolkit =
+
+== Objective ==
+
+Develop a simple, small-footprint GUI toolkit to build simple applications that are portable across platforms, especially mobile platforms.
+
+The '''exact same''' GUI source code should be portable across these platforms:
+ - Windows
+ - Windows Mobile Professional/PocketPC platform (i.e. with touch interface)
+ - Windows Mobile Standard/Smartphone platform (i.e. without touch)
+ - Symbian/S60 3rd edition
+ - (optional) console application
+ - (optional) Qt application
+
+== Basic idea ==
+
+The basic idea is to use XUL-like interface (see [http://www.mozilla.org/projects/xul/ XUL], and [https://developer.mozilla.org/en/XUL_Tutorial XUL tutorial]), but much more simplified.
+
+Sample interactions:
+
+ 1. Describe the window using XUL-like syntax (the code below is all over the place but hopefully you get the idea):
+    {{{
+const char *xml = 
+   "<?xml version="1.0"?>
+    <window id="mainwnd"
+            title="Hello world">
+      <label value="Press the button to exit"/>
+      <button id="btn_quit" value="Quit"/>
+    </window>";
+    }}}
+ 1. Create the window using the XUL XML description:
+    {{{
+window *wnd = create_window(xml);
+    }}}
+ 1. For modal dialog, start the dialog, giving it callback function to receive events from the window:
+    {{{
+do_modal(wnd, &event_handler);
+    }}}
+ 1. Do some code in the event handler:
+    {{{
+void event_handler(window *wnd, const pj_str_t *element, event *event)
+{
+   if (pj_strcmp2(element, "btn_quit")==0)
+      end_dialog(wnd);
+}
+    }}}
+ 1. And that's it!
+
+
+== The GUI elements ==
+
+Supported elements:
+ * window
+ * hbox and vbox
+ * spacer
+ * label (static text)
+ * command bar (will be translated into buttons or menu on interface with touch capability, or into menu on the rest)
+ * edit/input control
+ * combo box control (advanced)
+ * list control (advanced)
+
+Unsupported elements:
+ * button (it's only most usable with touch interface)
+
