c++ - putting a code-block-like control from App Inventor in desktop app -

i'm trying make simple program allows click , drag item 1 window, child window, another, parent window. it's going game level editor of sorts i'm working on video game need school project. have months it, i'm in no rush.

the thing i'm curious how i'll item child window parent window during runtime. can have buttons in child window place objects in parent window. original idea - having drag , drop functionality isn't necessary. want know if can images, in format similar app inventor - how writes code in background while fiddle around building window, placing various blocks down. version app inventor, it's in desktop application , there no words, pictures.

does winapi have control built in? if so, love know name or find information it. i'm not sure how begin search that, except site.

my original idea use picturebox controls, i'd either have litter entire window them , allow user click , drag them "move" them around while sets image 1 or other picturebox, while in background setting code automatically, or else. either way, i'm sure it's possible, doubt that's way want go.
