how to create Panel for Plot?

Question

Can You advice me how to put the whole thing below into an interactive Panel, so I can values of parameters dynamically - type other values (alpha, beta, x0, y0, R, tmax) and plot updates

α = 1.0;
β = 3.2;
x0 = Pi;
y0 = 0;
R = 0.3;
tmax = 2;
splot = StreamPlot[{z*(β - α*Cos[2*ϕ]), α*(1 - z^2)*Sin[2*ϕ]}, {ϕ, 0, 2 Pi}, {z, -1, 1}, StreamStyle -> GrayLevel[0.2], PlotRange -> {{0, 2 Pi}, {-1, 1}}, StreamPoints -> Fine, StreamScale -> Tiny, ImageSize -> 1000, FrameTicks -> {{{-1, -0.5, 0.0, 0.5, 1.0}, None}, {{0, Pi/2, Pi, 3 Pi/2, 2 Pi}, None}}, FrameTicksStyle -> Directive[Black, 16], FrameLabel -> {Style["ϕ", 18, Black, "Arial"], Style["z", 18, Black, "Arial"]}, AspectRatio -> 1/Pi];
flow = Function[{t, a, b}, Evaluate[{ϕ[t, a, b], z[t, a, b]} /. First@NDSolve[{D[ϕ[t, a, b], t] == z[t, a, b]*(β - α*Cos[2*ϕ[t, a, b]]), D[z[t, a, b], t] == α*(1 - z[t, a, b]^2)*Sin[2*ϕ[t, a, b]], ϕ[0, a, b] == a, z[0, a, b] == b}, {ϕ, z}, {t, 0, tmax}, {a, x0 - R, x0 + R}, {b, y0 - R, y0 + R}]], Listable];
circlePts = With[{n = 1000}, Table[{x0, y0} + R*{Cos[t], Sin[t]}, {t, 0, 2 Pi - 2 Pi/n, 2 Pi/n}]];
Manipulate[Show[splot, Graphics[GraphicsComplex[Dynamic@flow[t, circlePts[[All, 1]],  circlePts[[All, 2]]], {Opacity[0.6], Red, Polygon[Range@Length@circlePts]}]], AspectRatio -> Automatic], {t, 0., tmax}]
