Reverse queryobject()?

Lately I've been working on my own blitz gui editor that will inlcude user32.dll abillities (such as readonly text fields) for creating more advanced GUI's. However, I've run into a problem when it comes to detecting selection of text fields. I've found the getfocus() user32 command here: http://www.blitzbasic.com/Community/posts.php?topic=22605#239049, but I need a way to return the blitz handle of the hwnd because I have soooo many dynamically generated gadgets that using queryobject() on each of them just doesn't seem feasible. Any takers?

O.k., got past the last problem (ended up just using queryobject() on all of them). Now, I'm looking for a way to use pointers to access blitz+ variables. I tried creating my own userlib, but what should the return types for the functions be; and how do you return something that you can use as a pointer in blitz? I was thinking about having two functions in the userlib. One to get a pointer to the variable, and one to write integers to the variable. Anyone know the answers to the above to questions? Or, better yet, a different way than creating a userlib?

O.k. I decided just to use global variables instead of pointers... Although its rather brute force... Yet another question, however. I need a way to edit a gadget's style (and possibly the gadget's group as well) without freeing the gadget and recreating it. Obviously, if you free a gadget (such as a window) you will delete its children gadgets as well, and it wouldn't look very good to just remake *all* the gadgets that the user has created every time they decide that they DO need a menu on one of their windows after all. Hmm... anyone think I should just start a new thread for this project? I didn't want to hold too many of the top threads in the forum, but I'm not getting a very good response with the current title...
